Tape bronze Brb2

The tinless bronze processed by pressure of Brb2. Brb2 – a tinless bronze with high strength, wear resistance, electric and thermal conductivity. It represents the wrought copper alloy containing 2% of beryllium. Except the basic alloying element nickel, iron, silicon, aluminum and lead is its part. The Brb2 brand easily gives in to pressure treatment in the tempered state, cooks well and cut. On the level of hardness and elasticity it is possible to compare it with special stalyam. Heat treatment increases the strength and springing properties of an alloy Brb2. Also it possesses good anticorrosive, mechanical and antifriction properties. Small tendency to cold brittleness allows beryllium alloy to work in the big range of temperatures. To their shortcomings high cost, deficiency and toxicity are. This brand of bronze is applied to production of contacts, springs and other flexible parts. Generally it is used on the most responsible sites in flow processes and in expensive equipment. Quality and a type of delivery of an alloy of Brb2 corresponds: Non-ferrous metals, including rare, and their alloys of B51 of GOST 18175-78, GOST 28873-90, OST 4.021.009-92, TU 48-21-5062-89 Sheets and strips of B53 of GOST 1789-70, OST 4.021.069-92 Bars of B55 of GOST 15835-70, OST 4.021.024-92 Wire from non-ferrous metals and their alloys GOST 15834-77 B74, OST 4.021.108-92 Tapes B54 OST 4.021.082-92, TU 48-0812-12-89, TU 48-0812-15-90, TU 48-0812-26-89, TU 48-21-265-87, TU 48-21-743-92 Plastic metal working. Forgings of B03 of ST of TsKBA of 010-2004 V the chemical composition an alloy of Brb2 contains chemical elements in %: Fe to 0,15 Si to 0,15 Ni 0,2 - 0,5 Al to 0,15 Cu 96,9 - 98 Pb to 0,005 Be 1,8 - 2,1 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 Brb2: Hardness of material: HB 10-1 = 130 - 150 MPas Melting temperature, °C: 955 Application of an alloy of Brb2 in the industry: for production of semi-finished rolling (a tape, strips, bars, pipes and a wire); springs and elastic sensing elements in instrument making, the springing parts of responsible assignment; wear-resisting parts of all types; not sparking tools. Note: Brb2 beryllium bronze possesses high strength and wear resistance, good antifriction properties, very good deformability in the tempered state, average conductivity and heat conductivity. Analog of Brb2 bronze on SEV 377-76 is CuBe2Ni (Co) bronze. Buy the Tape bronze Brb2 legko:1. You send zayavku2. We expose to you schet3. You pay convenient for you sposobom4.
