Model casting alloy Combilium BSM 3 + 5
Cobilium BSM is available in two qualities:
- BSM 3 spring hard for combination work
- Optimal balance between strength and elasticity
- Excellent flow properties, even for delicate constructions
- Very easy to polish
- According to ISO 22674, free from beryllium and cadmium
- BSM 5 for combination work, extra hard
- Extra high hardness and rigidity
- Optimal balance between strength and elasticity
- Excellent flow properties, even for delicate constructions
- Very easy to polish
- Suitable for laser welding
- According to ISO 22674, free of beryllium and cadmium
Combilium BSM excels by virtue of its outstanding bending strength, high elasticity and fine flow behaviour. Combilium BSM features reduced oxide formation, can be finished easily and exhibits bright surfaces that can be polished well.
