Machining ratio of indium and zinc alloy aluminium product

The invention discloses a machining ratio of an indium and zinc alloy aluminium product. The aluminum product comprises, by mass percent, 2.5 to 4.5% of Zn, 0.018 to 0.05% of In, 0.005 to 0.025% of Cd, not larger than 0.1% of Si, not larger than 0.3% of Fe, not larger than 0.01% of Cu and the main component of AI. Sufficient melting of two elements of indium and zinc can be better achieved, meanwhile, uniform coordination of the alloy material during machining can be ensured, the condition that strength of aluminum alloy is not enough is avoided, meanwhile, the collision effect of mass of anode oxide films can be better reduced, the alloy can be better used for producing and machining, the variable appearing in the inner molecules due to extrusion can be avoided, stability of the interiorand the whole texture can be ensured, disorder of inner grain structures can be avoided, and practicability and excellence of the ratio scheme can be ensured. 本发明公开了一种铟锌合金铝材的加工配比，其主要成分与质量含量为：Zn，2.5％-4.5％、In，0.018-0.05％、Cd，0.0
