Abstract

The invention provides an aluminum-steel composite fastening disk. The aluminum-steel composite fastening disk is composed of an aluminum tube and a steel rod through explosive compounding to form a metallurgical composite surface, and then is cut to form an aluminum composite surface with an aluminum part and a steel part. The steel composite fastening plate is processed on the steel part to form a beam structure with fastening effect, and at the same time, the aluminum part can be welded with other aluminum fittings to realize the connection function. The aluminum-steel composite fastening disk provided by the invention has high strength, long service life and strong anti-corrosion ability. The preparation steps are simple and easy, the cost is low, and the invention has good application prospects and wide applications.

Description

technical field [0001] The invention relates to the technical field of bimetallic fasteners, in particular to an aluminum-steel composite fastening disc. Background technique [0002] Aluminum and aluminum alloy materials are widely used in construction, shipbuilding, vehicle manufacturing and other fields due to their good corrosion resistance, low density and light weight. In the fields of construction, shipbuilding, and vehicle manufacturing, aluminum and aluminum alloy materials have achieved large-scale applications. In a large number of applications, it is often necessary to install hooks on aluminum or aluminum alloy structures for operations such as structure installation, cargo fixing, and equipment positioning. Lashing discs are prone to breakage and have a short service life, especially in high-load environments, and aluminum fastenings are likely to pose a huge safety hazard. To solve this technical problem, welding technology can be used to connect aluminum or...
