Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.

We are engaged in making Lead available in several forms including
LME registered and non registered 99.97% and 99.99% as well as
secondary ingots, foil, granules, powder, rod, shot, sheet, and wire.
Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a
relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes
upon exposure to air. Alloys include pewter and solder.
We are able to supply Tin in many forms including LME registered and
non registered, ingots, slabs, bars, foil, granules, powder, anodized
activated powder, shot, wire, sticks, ingots, and “mossy tin”.
Tin is a silvery-white metal, is malleable, somewhat ductile, and has a highly crystalline
structure. The element has two colours, with a cubic structure which changes at
allotropic forms. On warming it is grey, the ordinary form of the metal. When Tin is
cooled below 13.2°C, it changes slowly from white to grey or tetragonal structure. This
change is affected by impurities such as Aluminium and Zinc, and can be prevented
by small additions of Antimony or Bismuth.
We hold immense expertise in making available Copper in many forms
including LME registered and non registered cathodes, billets, rods,
cakes, bars, foil, sheet, granules, plates, powder, shot, turnings, wire,
insulated wire, mesh and “evaporation slugs”.
Copper is one of the most important metals. Copper is reddish with a bright metallic
lustre. It is malleable, ductile, and a good conductor of heat and electricity (second
only to silver in electrical conductivity). Its alloys, brass and bronze, are very important.
Monel and gun metals also contain copper. The most important compounds are the
oxide and the sulphate, (blue vitriol

Galvanized GI Steel Rolls & Plates & Coils
Whatâ??s the difference between galvanized GI steel coils and plates?
I. Definition
Galvanized GI Steel coil and galvanized sheet are galvanized steel. The galvanized coil is a continuous hot dip galvanized coil in the production process. While galvanized sheet is a single hot dip galvanized sheet in the production process.
2. the production process
The production process of galvanized coil and galvanized sheet is different.
The production process of galvanized coil generally includes multiple processes such as coil heating, hot dip galvanizing and shearing into coil.
The galvanized sheet is generally the zinc alloy coating through the hot dip technology directly coated to the surface of the steel plate.
So the production process is relatively simple, the process difficulty is relatively low.
3. material thickness
The material thickness of galvanized coil and galvanized sheet is also slightly different.
Generally speaking, the thickness of galvanized coil is relatively thin. We mainly use it for the production of cold rolled, coating and other thin steel products.
The thickness of galvanized sheet is relatively thick. We mainly use it in the manufacture of glass fiber reinforced plastic, automotive panels, roof panels and other steel products requiring strength and corrosion resistance.
4. Advantages and Disadvantages
Both galvanized coil and galvanized sheet have their own advantages and disadvantages.
The production cycle of galvanized coil is short, the process is simple, and it is suitable for the production of low thickness and high precision steel products.
The galvanized sheet has the advantage of hardness, corrosion resistance, wear resistance and other multiple properties.
However, the production process of galvanized sheet is time-consuming and laborious, and the production cost is relatively high.
5. Application fields
The application areas of galvanized coil and galvanized sheet are also different.
Galvanized coil is usually used in the production of home appliances, building materials, auto parts, pipes and other high-demand steel products.
The galvanized sheet is mainly used in automobile manufacturing, construction engineering, petroleum, chemical and other industries.
In addition, because of the good corrosion resistance of galvanized sheet, it is also widely used in Marine engineering, railway, bridge and other fields.
