Hardness of 229-291 Brinell (Al-Bron)
The minimum iron component does not make it 100% non-magnetic, although its low magnetism makes it suitable for low and non-critical magnetism applications.
The durability of aluminum-bronze is not as great as Cu-Be.
Tensile strength: 800 N / mm2.
Length of tip: 80 mm
