L90 - SuZn10 - C52400 sheet, strip, tube

general characteristics

Complexly brass L90 refer to double pressed brass, as the marking has a very high percentage of copper in the alloy is about 90%. In a series of pressure treated alloy has good resistance to corrosion. Widely used in the production of semi-finished products such as tubes, sheets, strips, bars, used in instrumentation, electrical engineering, as well as for forging, enamelling and minting of medals, badges and so on. N.

Production

The chemical composition of grade L90 normalized GOST 15 627−2004. The alloy comprises the following components: the main part of copper is 88 — 91%, zinc is contained in an amount of 8 — 12%. Dopants are listed in descending order. Iron — 0.1%, lead — up to 0.03%, phosphorus 0.01, Sb — 0.005%, 0.002% bismuth, impurities — not more than 0.2%. Alloy melts at t ° 1045 ° C, processed at t ° 700 — 850 ° C, the annealing temperature is 450 — 600 ° C.

dignity

Brass hire has a number of advantages over the more expensive copper. In particular, brass L90 has a high strength, a very well-deformed in the cold state, is not prone to stress corrosion cracking; widely used for stamping, forging, enameling. Mechanical strength at t ° 20 ° C: the tape (GOST 8036 — 79) has s _at 250 MPa, d ₅ 38%; strip cold-rolled soft (GOST 931 — 90) s _s = 230 — 340 MPa, d ₅ 36%; and cold-rolled strip solid (GOST 931 — 90) s _s = 350 MPa, d _{May 3%.}
