Introduction
Pure Zinc & Zn/5Al are excellent material choices for corrosion protection in both atmospheric and marine environments. Using either the electric arc spray or combustion wire process, wire coatings of these materials
act as sacrificial anodes, galvanically protecting iron or steel substrates.Decades of field work using these coatings has clearly demonstrated that they are far more effective and longerlasting than hot dip galvanizing.
Coatings of ZnAl often have better corrosion resistance than either pure zinc or aluminum, by combining the advantages of both materials. This is particularly true in areas where crevices exist and residual moisture and contamination is present, and in areas where the coating has been scratched or scraped, resulting in coating voids and exposed substrate.
Using the electric arc spray process, coatings of these materials are often used in the electronics industry for EMI and RF shielding, or as conductive coatings on capacitors.
Typical Uses and Applications
Atmospheric and immersion corrosion protection on large steel or iron structures such as bridges, roadway
barriers, posts and poles, offshore structures and marine structures.
Atmospheric corrosion protection on steel or iron components such as tanks and gas bottles
EMI and RF shielding on plastic components (electric arc spray only)
Electrical conductance on components such as the Conductive areas on insulators and capacitor end caps

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 put forward a high quality of assortment of Nickel which is available in many forms including LME registered and non registered cathodes, cut cathodes, briquettes, pellets, disks, shots, granules, foil, powder, flakes, sheet, wire, mesh, spheres, “evaporation slugs”, and rods. Nickel is a silvery white metal that takes on a high polish. It is hard, malleable, ductile, somewhat ferromagnetic, and a fair conductor of heat and electricity
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.
The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste. After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container. Please feel free to contact us for further details.
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.
