Cube2--C17200 (CDA 172) Beryllium Copper is the most commonly utilized Copper Beryllium alloy and is notable for its highest strength and hardness compared to commercial copper alloys. C17200 alloy contains appr. 2% of beryllium and achieves its ultimate tensile strength can exceed 200 ksi, while the hardness approaches Rockwell C45. Meanwhile, the electrical conductivity is a minimum of 22% IACS in the fully aged condition.C17200 also exhibits exceptional resistance to stress relaxation at elevated temperatures.

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

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 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.
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.
