Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical and electrical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
In contrast, bronze is an alloy of copper and tin. Both bronze and brass may include small proportions of a range of other elements including arsenic, lead, phosphorus, aluminium, manganese, and silicon. The distinction is largely historical. Modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the all-embracing ``copper alloy``.
Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
Aluminium or aluminum is a chemical element with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic and ductile metal in the boron group. By mass, aluminium makes up about 8% of the Earth's crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. The chief ore of aluminium is bauxite. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.
Stainless Steel & Nickel Alloys Scrap
Stainless steel is a steel alloy with increased corrosion resistance compared to other steel Alloy. Common alloying ingredients include Nickel, Chromium and/ or molybdenum and Steel. Due to its corrosion resistance properties the common applications include food handling/processing, medical instruments, hardware, appliances, and structural/architectural uses. Stainless steel’s resistance to corrosion and staining, low maintenance make it an ideal material for many applications where both the strength of steel and corrosion resistance are required.100% of the Stainless Steel scrap can be recycled without losing its value. Currently 90% plus is recycled and balance will be lost in the system. We buy and sell all kindly of Stainless Steel Alloys predominantly 200,300 & 400 series. We also do High Temp Alloys such as Monel, Inconel, Hastelloy etc. Material can be in any form such as Shredded / Un-shredded Solids, Turnings and in any form such as Loose, HRB Bales, Soft Bales, Briquetted etc.
