[0023] Example 1
[0024] The specific mass percentage composition of the alloy composition of the present invention:
[0025] Copper 66%
[0026] Iron 3%
[0027] Aluminum 6%
[0028] Manganese 3%
[0029] Nickel 6%
[0030] Yttrium 0.025% + vanadium 0.03% + boron 0.025%, the balance is zinc and inevitable impurities.
[0031] The specific manufacturing method of smelting high-strength and toughness aluminum brass alloy provided by the present invention includes the following steps:
[0032] The high-strength and toughness aluminum-brass alloy provided by the present invention is compounded by mass percentage. The raw materials are electrolytic industrial pure copper, aluminum, manganese, nickel and iron (select oil-free and rust-free iron wire or iron nails), and copper-boron, copper- Master alloys such as yttrium, aluminum-vanadium, etc., by adjusting the amount of master alloy added to control the total content of the three metal elements of yttrium, vanadium and boron in the high-stre...
