Abstract

The invention discloses a double-layer composite durable mechanical bearing alloy for electric fittings. The double-layer composite durable mechanical bearing alloy comprises interior high-strength pipe casting alloy and exterior high-hardness pipe casting alloy, wherein the high-strength pipe casting alloy is composed of, by weight, 38 to 42 parts of iron, 17 to 20 parts of nickel, 6 to 9 parts of silicon and 8 to 11 parts of manganese while the high-hardness pipe casting alloy is composed of, by weight, 28 to 32 parts of chromium, 9 to 12 parts of molybdenum, 45 to 48 parts of iron and 13 to 16 parts of titanium. The interior of the double-layer composite durable mechanical bearing alloy is high in strength and good in thermal performance; and the exterior of the alloy is high in hardness, good in wear resistance, strong in toughness and long in service life.

Description

technical field [0001] The invention relates to a durable alloy for double-layer composite mechanical bearings for electrical accessories. Background technique [0002] In recent years, China's foundry equipment industry has achieved rapid development. The molding equipment has made great progress in terms of product performance, reliability, and automation, and is gradually moving towards green casting. [0003] Most of the various materials used in the prior art are produced independently of a single structure when they are manufactured into various products, and the use of composite materials is relatively lacking, and the quality of the products themselves in the prior art is also uneven, and the use effect is lacking . Contents of the invention [0004] The purpose of the present invention is to provide a durable alloy for double-layer composite mechanical bearings for electrical accessories with high internal strength, good thermal performance, high external hardnes...
