See all Blog Posts Red Metal Grade Guide Category: Brass, Bronze, Copper Posted: April 23, 2018 Trying to determine what red metal you should use for your next project? Our Red Metal Grade Guide breaks down some of the most common red metal grades. Copper BS BS EN Description C101 CW004A Electrolytic Tough Pitch (ETP) is a commonly used grade of copper for electrical applications. C103 CW008A Oxygen Free Copper is an oxygen free copper with a minimum copper content of 99.95%. C106 CW024A Phosphorus De-oxidised Copper has the oxygen removed through the controlled addition of phosphorous, making it more easily weldable. C109 CW118C Tellurium Copper (free cutting) has 0.5% tellurium which raises the machinability but has a limited effect on both ductility and conductivity. C110 CW009A Oxygen Free (High Conductivity) Copper contains 99.99% copper with limited impurities when compared to other grades. This grade is the purest of the oxygen free coppers. C111 CW114C Sulphur Copper (Free Machining) has a machinability rating of approximately 80% which is due (in part) to the addition of sulphur. C101AG2 CW011A Silver-Bearing Copper features the addition of copper to improve the resistance to softening. These grades also feature improved electrical conductivity and resistance to heat and corrosion. C101AG3 CW012A C101AG4 CW013A CC102 CW106C Copper Chrome Zirconium contains small amounts of zirconium as well as chromium which help to improve mechanical performance. Brass BS BS EN Description CZ101 CW501L Gilding Metal contains 90% copper and 10% zinc. It possesses good cold working and strong stress corrosion resistance. CZ106 CW505L Cartridge Brass has a zinc content of approximately 30%. It possesses excellent ductility, strength and cold workability. CZ108 CW508L Basis Brass Possesses hot and cold working capabilities as well as good corrosion resistance and machinability at slow speeds. It is commonly used for simple forming applications. CZ112 CW712R Naval Brass has good corrosion resistance in salt water and other corrosive environments. It contains approximately 62% copper, 37% zinc and 1% tin which helps to improve the corrosion resistance. CZ114 CW721R High Tensile Brass contains aluminum, iron and manganese which increase the strength. The aluminum also aides in the forming of an aluminum oxide film on the surface which increases the corrosion resistance. CZ115 CW722R High Tensile Brass (Restricted Al) has restricted aluminum content which aides in brazing and soldering. Additional alloys including iron and tin help to improve the strength. CZ120 CW608N Engraving Brass features the addition of lead at approximately 2% by weight which helps with free cutting properties. CZ121 CW614N Free Machining Brass possesses 3% lead content which gives the grade excellent machinability. CZ122 CW617N Stamping Brass contains 59% copper, 39% zinc and 2% lead. It possesses excellent hot working and machining capabilities. CZ129 CW611N Bending Brass possesses excellent hot working properties as well as formability, machinability, strength and ductility. CZ131 CW606N Turning and Riveting Brass features a fine dispersion of lead which helps with machinability. This grade also possesses good ductility, strength and corrosion resistance. CZ132 CW602N Dezincification Resistant Brass contains small amounts of arsenic and lead. It possesses good strength and can be machined and hot forged. Bronze BS BS EN Description PB102 CW451K Phosphor Bronze contains approximately 5% tin and up to 0.4% phosphorus which increases wear and corrosion resistance, mechanical strength, and stiffness. PB104 CW453K High Performance Wrought Phosphor Bronze possesses a high tin content of approximately 8% along with phosphorus which provides excellent wear, fatigue and corrosion resistance. PB1 CC481K Nickel Tin Bronze possesses high mechanical strength with good ductility, as well as corrosion and wear resistance. It contains approximately 10.2% – 1.5% tin. LG1 CC490K Leaded Tin Bronze (Leaded Gun Metal) provides good corrosion resistance in water applications and at high temperatures. It also possesses excellent machinability and wear resistance. LG2 CC491K Phosphor & Leaded Bronze (Leaded Gun Metal) is the most commonly used leaded gun metal grade. It possesses good machinability and wear resistance. It also offers some corrosion resistance in marine applications. LB4 CC494K Leaded Tin Bronze has excellent machinability due to the additions of 9% lead and 5% tin. It also features good corrosion resistance and medium strength. C932 CC497K Bearing Bronze (SAE 660) is the most commonly used bronze in bushing and bearing applications. It easy to machine, and provides long life span, where wear is a important factor. CA104 CW307G Aluminum Bronze possesses excellent corrosion and erosion resistance in salt water applications. This grade also has high strength and good wear and abrasion resistance.
