Description

Bronze БрБ1,9НТ used: for the manufacture of semi-finished products (strips and stripes); the springs and elastic sensing elements in instruments, spring details of responsible destination; wear-resistant parts of all kinds; non-sparking tools.

Note

Beryllium bronze Brbnt1,9 has high strength and wear resistance, good sliding properties, very good deformability in the hardened state, the average electrical conductivity and thermal conductivity.
Analogue of bronze Brbnt1,9 at the CMEA 377−76 is bronze CuBe2NiTi.
