L70 - 2.0265 - SuZn30 rod, tape, wire

general characteristics

Complexly brass L70 refer to double pressed brass. As can be seen from the markings L70 has a high percentage of copper in the alloy is approximately 70%. Among others. Alloy has good corrosion resistance, is easily deformed in the cold state, easily soldered is suitable for application to the steel. It is used for the manufacture of semi-finished products such as sheet, strip, strip, tube, wire.

Production

The chemical composition of grade L70 normalized GOST 15 627−2004. The alloy comprises the following components: the main part of copper is 69 — 71%, zinc is contained in an amount 28 — 30%. Dopants are listed in descending order. Iron — 0.07%, lead — up to 0.05%, 0.005% phosphorus, antimony, bismuth and 0.002% impurities — not more than 0.2%. Alloy melts at t ° 950 ° C, is treated at t ° 700 — 850 ° C, the annealing temperature is 550 — 650 ° C.

dignity

Brass hire has a number of advantages over the more expensive copper. In particular, brass L70 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: soft sheet (GOST 2208 — 2007) has s ₂₇₀ — 360MPa, d ₅ to 40%; solid sheet (GOST 2208 — 2007) s _B = 430 MPa, d _{October 5%;} Semisolid a pipe (GOST 21646 — 2003) s _B = 340 MPa, d _is 5 to 35%.

Using

L70 Brass is used for manufacturing using deep-drawn semi-finished products such as sheet, strip, strip, tube, wire, which are used for heat engineering equipment, Radiator tapes, musical instruments parts. stamping method. manufactured liner including chemical apparatus.
