Abstract

The invention relates to high-strength aluminum alloy for an elevator, which comprises metal elements by weight: 0.05 to 0.5 percent of silicon, 0.1 to 1 percent of magnesium, 0.5 to 2.5 percent of copper, 0.05 to 0.1 percent of ferrum, 0.01 to 0.05 percent of zinc, 0.1 to 0.5 percent of La, 0.05 to 0.15 percent of Zr, 0.01 to 0.05 percent of tin, 0.01 to 0.05 percent of Cr, 0.1 to 0.5 percent of silver, 0.5 to 1.5 percent of strontium, and Al in balancing amount. The aluminum alloy section obtained through the high-strength aluminum alloy is high in strength, enables the deflection and the swing of a lifting table to be very small, and has superhigh load-carrying ability and excellent working stability.

Description

technical field [0001] The invention relates to a high-strength aluminum alloy suitable for elevator hoists. Background technique [0002] Elevator lifts are generally made of high-strength aluminum alloy materials, which require small size, light weight, stable lifting, safety and reliability. However, the conventional high-strength aluminum alloy has high stress corrosion sensitivity in its high-strength Tg state, which is easy to cause sudden damage. Since stress corrosion cracking is mainly a hydrogen-induced fracture process, the hydrogen of high-strength aluminum alloy The problem of brittleness has been receiving attention. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-strength aluminum alloy for an elevator hoist, which has high strength and high toughness, and can ensure the stable operation of the elevator. [0004] In order to solve the problems of the technologies described above, the p...
