Nordic Gold, composed of 89% copper, 5% aluminium, 5% zinc, and 1% tin, is a more recently developed aluminium-bronze alloy for coinage. It was first used for the Swedish 10-kronor coin in 1991, and became widespread after the introduction of Nordic gold 10, 20 and 50-cent Euro coins in 2002.
They are generally about 10 percent denser than steel, although alloys using aluminum or silicon may be slightly less dense. Bronze conducts heat and electricity better than most steels. Copper-base alloys are generally more costly than steels but less so than nickel-base alloys.
Aluminium brass is a technically rather uncommon term for high-strength and partly seawater-resistant copper-zinc cast and wrought alloys with 55–66% copper, up to 7% aluminium, up to 4.5% iron, and 5% manganese. Aluminium bronze is technically correct as bronze, a zinc-free copper-tin casting alloy with aluminium content.

A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%. Iron, nickel, manganese and silicon are sometimes added.

Fluid. Capable of bridging larger gaps than pure copper (up to 0.7 mm in extreme cases). 97: 3: 0.05: Cu 99 Ag 1: Cu 1070/1080 [1] – CU 106. Slightly lower melting point than pure copper. More expensive due to silver content. Rarely used now. Can be used after CU 105 in step brazing. 99: 1: Cu 95 Sn 4.7 P 0.3: Cu–Sn 953/1048 [26] – CDA ...
