Copper

MOQ: Not Specified
Supplier From Navi Mumbai, Maharashtra, India
 
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

Zinc

MOQ: Not Specified
Supplier From Navi Mumbai, Maharashtra, India
 
We offer a wide plethora of Zinc in many forms including LME registered
and non registered Special High Grade Ingots and Jumbos, cathodes,
dust, foil, granules, powder, pieces, anodize activated powder, shot,
and a mossy form.
Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is
malleable at 100 to 150°C. It is a reasonable conductor of electricity, and burns in air
at high red heat with evolution of white clouds of the oxide. Plating thin layers of zinc
on to iron or steel is known as galvanizing and helps to protect the iron from corrosion.

Lead

MOQ: Not Specified
Supplier From Navi Mumbai, Maharashtra, India
 
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.

Stainless Steel Tube

$0.50 - $10
MOQ: 100  Pieces
Sample Available
 
Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration.
Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe.
Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes.
It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.
