It is entirely possible that a sword of legendary Achilles was forged out of hardened beryllium copper.

Merits of bronze alloy Cu2Be

Grade: tinless, pressure-treated bronze. Cu2Be possesses high level of strength and durability, excellent antifriction characteristics, resistance to corrosion, perfect deformability. It is strengthened in hardened condition.

Industrial usage: manufacture of springs, elastic parts.

Percentage composition of alloy according to GOST 18175 -78

Element Content
Cu 96.9 — 98
Pb ≤ 0,005
Be 1.8 — 2.1
Fe ≤ 0,15
Si ≤ 0,15
Ni 0.2 — 0.5
Al ≤ 0,15

Main properties

Alloy hardness: HB 10 -1 = 130 — 150 MPа

Point of melting: 995°C

Tinless bronzes including Cu2Be alloy do not contain a scarce tin in its composition. However, they are often superior to other non-ferrous alloys by their consumption possibilities.
Tinless bronzes can be not only beryllium but manganese or aluminium as well, depending on the main alloying component. Beryllium coppers are manufactured in accordance with GOST 18175−78. This standard is applied to pressure-treated tinless bronzes which intended for a manufacture of sheet and flat mill-products.
