Plug bronze Brazh9-4

The tinless bronze processed by pressure of Brazh9-4. BrAZh9-4 – a tinless bronze with high anticorrosive and mechanical properties. This brand represents the wrought copper alloy containing 9% of aluminum and 4% of iron. Except the basic alloying elements the insignificant amount of manganese, zinc, silicon, tin, phosphorus and lead is its part. BrAZh 9-4 bronze easily gives in to pressure treatment in a hot state, possesses high strength and good antifriction properties. Now it is widely applied in an aircraft industry and mechanical engineering. Quality and a type of delivery of an alloy of Brazh9-4 corresponds: Non-ferrous metals, including rare, and their alloys of B51 of GOST 18175-78, GOST 28873-90, OST 4.021.009-92 Bars of B55 of GOST 1628-78, OST 4.021.021-92 Pipes from non-ferrous metals and alloys of B64 of THAT 48-21-39-79 V the chemical composition an alloy of Brazh9-4 contains chemical elements in %: Fe 2 - 4 Si to 0,1 Mn to 0,5 P to 0,01 Al 8 - 10 Cu 84,3 - 90 Pb to 0,01 Zn to 1 Sn to 0,1 On some properties tinless bronzes exceed tin. Aluminum, silicon and especially beryllium bronze — on mechanical properties, aluminum — on corrosion resistance, kremnetsinkovy — on flowability. Aluminum bronze thanks to beautiful golden-yellow color and high corrosion resistance sometimes is also applied as gold substitute to production of costume jewelry and coins. Durability of aluminum and beryllium bronze can be increased by means of heat treatment. Physical, technology and mechanical properties of an alloy Brazh9-4: Hardness of material: HB 10-1 = 100 - 120 MPas Melting temperature, °C: 1040 Friction coefficient with lubricant: 0.004 Friction coefficient without lubricant: 0.18 Application of an alloy of Brazh9-4 in the industry: for production of semi-finished rolling (tapes, strips, bars and a wire); gear wheel, plugs, saddles of valves in an aircraft industry; castings of massive parts to the earth of the general mechanical engineering. Note: Bronze corrosion-resistant, possessing high mechanical properties and good antifriction properties. Analog of BrAZh9-4 bronze on SEV 377-76 is CuAl9Fe4 bronze.
