Brof 6.5-0.15 tape, strip

Brof 6.5-0.15 tape, strip

Industrial use: for bushings, springs and bearings

Brof6.5−0.15 — belongs to the class of tin bronze, processed under pressure.

Characteristics of tin bronzes

Bronze tin have elevated anti-friction quality, they are non-magnetic, cold-resistant, insensitive to overheating, have low volume shrinkage (about 0.8%), so widely used in art casting. The main disadvantage of tin bronzes is the formation of small pores in castings that may result in reduction tightness. Bronze tin lagerbuchse lead, zinc, Nickel, phosphorus.

Vyplavke

In the smelting process of copper and tin is formed solid solutions strongly prone to phase separation due to the high temperature interval of crystallization. Containing tin alloys over 5% have in its structure due to segregation eutectoid component e (a+d), which consists of hard and soft phases.

Basic quality

The structure of this alloy is for parts favorable sliding bearings: solid particles provide abrasion resistance, the soft phase gives excellent pererabatyvaemogo, therefore, tin bronze are excellent antifriction materials.

The coefficient of friction with lubrication is 0.01

The coefficient of friction without lubrication is 0.12

Hardness of alloy: HB 10-1 = 70 — 90 MPa

Melting point: 995°C
