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.
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
Characteristics: White powder or tiny crystalls, nodorousand salty, easily soluble in water,insoluble in alcohol, presenting slightly alkalinity, decomposed when heating. Decomposed slowly when exposed to moist air.
