Base metals are common metals that tarnish, oxidize, or corrode relatively quickly when exposed to air or moisture. They can be contrasted with precious metals and are widely used in commercial and industrial applications, such as construction and manufacturing.
Examples of base metals include Lead, Copper, Nickel, Aluminum, Zinc & Tin
Antimony Ingots
Antimony Ingots, commonly known as fine antimony. Mainly used as an alloy hardener for metallurgy, battery, and military industry, but also the production of antimony oxide raw materials. Antimony Ingots are also used in the movable type printing industry, lead material, cable sheath, solder, and sliding bearings. Antimony is a kind of non-ferrous heavy metal, crisp and glossy silver-white solid. There are two allotropes, the yellow variant is stable at minus 90 degrees, and a metallic variant is a stable form of antimony. Melting point 630 degrees, poor heat conduction
Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid.
Calcium Aluminum Alloys
Calcium aluminum alloys use aluminum ingots and reduced calcium blocks as raw materials. Calcium aluminum alloy has a metallic luster and lively properties. It is mainly used in metal smelting as intermediate alloy refining and reducing agent. The content of metal calcium fluctuates in a small range, and the calcium aluminum alloy must not have segregation. The harmful impurities need to be controlled within a reasonable range, and there should be no oxidation on the surface of the alloy.
Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth’s crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin calx “lime”, which was obtained from heating limestone.
Lead Ingots
Lead ingots are distinguished by size, large ingots and small ingots, and the purity of lead content is over 99.994%. Lead ingots should be shipped in non-corrosive transport vehicles, protected from rain. Lead ingots should be stored in a ventilated, non-corrosive storage room. During the transportation and storage of lead ingots, the white, off-white or yellowish-white film formed on the surface is determined by the natural oxidation properties of lead, and is not a basis for scrapping
Selenium Metal Granules
Selenium is a chemical element with the symbol Se and atomic number 34.
Exists in two forms: a silvery metal or a powder.
Red selenium is an amorphous, glass-like solid, whereas grey selenium is a soft, bluish-grey metal.
Grey selenium is a semiconductor. Its electrical conductivity increases on exposure to light, reverting to its normal value in darkness.
Tin Ingots
Tin is a chemical element with the Symbol Sn. Tin is produced by carbothermic reduction of the oxide ore with carbon or coke. Tin is a silvery metal that characteristically has a faint yellow hue. Our Tin is proven and trusted by the world’s leading electroplaters
Tin (II) Sulfate
Tin(II) sulfate (SnSO4) is a chemical compound. It is a white solid that can absorb enough moisture from the air to become fully dissolved, forming an aqueous solution; this property is known as deliquescence.
