The constituent includes Al 100, Cu 0.15-0.35, Zn 0.05-0.25, Ti 0.01-0.04, and Si 0.4. The invention could be used as the band board of the plane connector.
Description
Technical field
The present invention relates to a kind of dedicated aluminium alloy band plate of space flight junctor.
Background technology
Long induction period aluminium alloy is the proprietary material of space flight junctor, but because original 500 regrate machines extend service in the army already, can not provide enough qualified product effectively, for guaranteeing the normal development of space industry, special this product of development.
Summary of the invention
The purpose of this invention is to provide a kind of new component aluminium alloy, satisfy the needs of space industry.
Above-mentioned purpose realizes by following technical scheme:
Long induction period aluminium alloy is made up of 100 parts of aluminium, 0.15-0.35 part copper, 0.05-0.25 part zinc, 0.01-0.04 part titanium and 0.4 part of silicon by ratio of weight and the number of copies; Control its foreign matter content: the iron corresponding with the aluminium of per 100 parts by weight is less than 0.5 part, manganese: 0.45-0.65 part.
This technical scheme has following beneficial effect:
1. product performance of the present invention are stable, can satisfy the particular requirement of space flight and military industry development fully, and its back 48 hours hardness of quenching does not have noticeable change, HB≤40, and the hardness after the moulding can reach HB 〉=92, simultaneously, on every military project performance index, all surpassed original product.
2. the present invention can provide long induction period type aluminium alloy extruded band plate, and squeezed state is H112, and regular size is 32 x, 15 x 2000mm
3With 44 x, 15 x 20000mm
3Deng.
