Concept

Co-Be

Al-Br

Hardness

35-40HRC

25-30HRC

Magnetism

Non ferrous substance in the composition makes it safer when non-magnetic applications are required

Minimum ferrous component makes them not 100% non-magnetic, although its low magnetism make it proper for non critical non-magnetic applications

Durability

Much higher due to the higher hardness and tensile strength. Higher efforts can be afforded

Not as much as Co-Be

Price

Higher price due to the special raw material used

Around 30% lower price
