2014 Aviation Aluminum Alloy for Sale
Aluminum Alloys Used in Aerospace Industry
3.jpgThe deformed aluminum alloy can withstand pressure processing, and can be processed into various shapes and specifications, which are mainly used to manufacture aviation equipment. Deformable aluminum alloys are further divided into non-heat-treatable reinforced aluminum alloys and heat-treatable reinforced aluminum alloys.

Heat-treatable reinforced aluminum alloys can improve mechanical properties through heat treatment methods such as quenching and aging. It can be divided into duralumin, forged aluminum, super-duralumin, and special aluminum alloys. Aviation aluminum alloys are mainly deformable aluminum alloys that can be heat treated, such as 2014 and 7050 aluminum sheet.

2014 Aluminum Alloy
The main element of 2014 aluminum alloy which has high strength and good cutting performance, but its corrosion resistance is poor. It is widely used in aircraft structures, including skins, rib beams and bulkheads, and the first stage fuel tank of the multi-stage rocket. 2014 Aluminum has five common tempers: O, T3, T4, T351 and H112.

Aluminum 2014 Price

The aluminum 2014 price consists of two parts: the average closing price of A00 aluminum ingots on the Yangtze River and processing fees. As the price of aluminum ingots fluctuates daily, the quotation will fluctuate.

Hongchang Aluminum supplies aluminum sheets and coils for the manufacture of bottle caps, which are ideal materials for PP caps for whiskey bottles and other beverage bottles. It has excellent moisture-proof, anti-seepage and anti-counterfeiting properties, making it truly safe, healthy, fast and environmentally friendly, increasing the added value of the product.

The production of PP bottle caps has strict requirements on the strength, elongation and dimensional deviation of the material, otherwise cracks or creases will appear during the processing. In order to ensure the convenience of printing after the bottle cap is formed, the surface of the bottle cap material is required to be smooth. No roll marks, scratches and stains. Commonly used alloys include 8011-H14, 8011-H16, etc. Aluminum bottle cap materials can be produced by hot rolling, continuous casting, continuous rolling or cold rolling.
8011 aluminum closure plates are used to manufacture screw cap systems for bottles and other containers and are one of the main products in the aluminum packaging market. Aluminum's airtight and light-tight properties and ease of shaping and decoration make it the material of choice for enclosed applications.

Aluminum PP lids are used for glass containers including mineral water, natural water, non-alcoholic and alcoholic beverages, health supplements and juice products.

3105 aluminum alloy is a typical deep-drawn material. The aluminum content is up to 98%, which can belong to the category of pure aluminum alloy, which is slightly stronger than the 1 series alloy with aluminum content of about 99%. Similarly, 3105 aluminum alloy cannot be strengthened by heat treatment, but its corrosion resistance, formability and welding properties are also excellent. Therefore, 3105 aluminum alloy is commonly used in the manufacture of residential wall panels, mobile homes and rain gear, bottle caps, lamp headstocks, shutters, etc. In addition, it is also used for sheet metal work. However, 3105 aluminum alloy has medium machinability, so lubricating oil treatment is required in all machining operations. And most importantly, 3105 aluminum alloy temper also affects the machinability required for our different applications. For example, the (H) harder temper is better than the 3105 aluminum alloy in the (O) annealed temper. But no matter how tempered the 3105 aluminum alloy is, the forming characteristics of the 3105 aluminum in all conventional processes are very good.

Calcined Bauxite,refractory Kiln Bauxite,80~90
Calcined bauxite is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 - 1800 degree Celsius.In this calcination process the high refractory mineral phases corundum and mullite are formed. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.

Bauxite the main component is alumina, aluminum hydrate contains impurities alumina, is a kind of earthy mineral, white or gray white, because of iron and brown yellow or light red. Extremely difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used in aluminum smelting, refractory system.

5052 aluminum coils is Aluminum-magnesium alloy aluminum coils. Mg is the main alloying element in 5052 aluminum coils. It is the most widely used rust-proof aluminum. The alloy is high in nature, especially fatigue resistance, plasticity and corrosion resistance, with high strength. It can not be heat-treated, the plasticity of it is good in semi-cold hardening. It s low in plasticity during cold hardening, and good in corrosion resistance with good weldability, poor machinability and polishing.
The main alloying element of 5052 aluminum sheet is magnesium, and aluminum-magnesium alloy also contains a small amount of Mn, Cr, Ni, Ti, etc. Most of the Mn in the alloy forms MnAl6 except for a small amount of solid solution. In the interior of the 5052 aluminum coils, the effect of Cr is similar to that of Mn, which improves the resistance to stress corrosion cracking, improves the strength of the base metal and weld, and reduces the tendency of weld cracking, but its content generally does not exceed 0.35%.
Surface Advantages of 5052 Aluminum coils:
1. surface of 5052 aluminum coils is not allowed to have cracks, corrosion spots and traces of nitrate.
2. The surface is allowed to have peeling, air bubbles, surface roughness. and it is also allowed to have local mechanical damage with a depth not exceeding 8% of the nominal thickness of the part where the defect is located. But the maximum depth of the defect shall not exceed 0.5 mm, and the total area of the defect shall not exceed the total area of the coils 5%.
3. Allow the supplier to illuminate the profile longitudinally to a smooth surface.
4. Other requirements: There are demanders and suppliers to draw up their own.
Application of 5052 Aluminum coils:
5052 aluminum coils is mainly used for high plasticity with good weldability. It is also commonly used in transportation vehicles, ship sheet metal parts, instruments, street lamp brackets and rivets, hardware products, electrical enclosures, etc. It can also be used to manufacture aircraft fuel tanks, oil pipes, aerospace aluminum alloy materials, and is a typical rustproof alloy material.
The atates of 5052 aluminum coils includes F, O, H12, H14,, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36, H38, H111, H112, H114.

3003 aluminum coil is the most widely used aluminum alloy. It is made up of aluminum, copper, iron, manganese, silicon and zinc. It is commonly used because it has great resistance to corrosion and is moderately strong. The 3003 aluminum coil is 20% stronger than 1100 grade alloys because it is fused with manganese.

Because it s not heat treatable, it has to be strengthened using cold working alone.
The most common applications for the 3003 aluminum coil are for fuel tanks, sheet metal work and other types of projects that need a metal that is stronger than the 1100 series aluminum. In some cases, it is used for cooking utensils, refrigerator panels, gas lines, storage tanks, garage doors, builder s hardware and awning slats.

Welding grade bauxite
Welding grade bauxite has tight regulation on presence of sulfur and phosphorus which are detrimental to the weld. When present at high concentrations, they induce porosity and cracking, and at lower concentrations, they adversely affect the impact strength of the weld. And moisture for welding grade bauxite should not exceed 0.5% because the potential for any moisture present withthin the flux to reduce to hydrogent, if exposed to a welding arc, the molten weld pool absorbs the hydrogen and will induce brittleness into the weld.

Application
Welding fluxes are a small but valuable market for calcined bauxite. Techniques for submerged arc welding require the use of a granular flux to shield the molten weld pool rom the atmosphere during the weldâ??s application or pacement. Various proprietary compositions exist and in some cases calcined bauxite is incorportated into these formulations. Calcined bauxite may, in some instances, make up to 25% of the welding flux.
