Wear-resistant Alloy Button PM Sintered Parts

Product Introduction

Powder metallurgy is mainly suitable for the production of spare parts and research-related raw materials and auxiliary materials in the fields of the automobile industry, equipment manufacturing industry, metal industry, aerospace, military industry, instrumentation, hardware tools, electronic appliances, etc., various powder preparation equipment, Sintering equipment manufacturing. Products include bearings, gears, carbide-cutting tools, molds, friction products, and so on. In military-industrial enterprises, heavy equipment such as armor-piercing bombs, torpedoes, etc., and brake pairs of aircraft and tanks all need to be produced by powder metallurgy technology. Powder metallurgy auto parts have become the largest market in China's powder metallurgy industry in recent years, and about 50% of auto parts are powder metallurgy parts.

(1) Application: (automobiles, motorcycles, textile machinery, industrial sewing machines, electric tools, hardware tools, electrical appliances, construction machinery, etc.) various powder metallurgy (iron-copper-based) parts.

(2) Classification: powder metallurgy porous materials, powder metallurgy anti-friction materials, powder metallurgy friction materials, powder metallurgy structural parts, powder metallurgy tooling and mold materials, powder metallurgy electromagnetic materials and powder metallurgy high-temperature materials, etc.

Cemented carbide is mainly used for cutting tools, such as turning tools, milling cutters, and so on. The more carbide content in cemented carbide and the less cobalt content, the higher the hardness, thermal hardness, and wear resistance of the alloy, but the lower the strength and toughness. YG alloys are suitable for processing brittle materials, and YT alloys are suitable for processing plastic materials. Among the same alloys, those with high cobalt content are suitable for rough machining, and those with low cobalt content are suitable for finishing.

Cemented carbide is also used to make cold working dies, such as cold drawing dies, cold stamping dies, cold extrusion dies and cold heading dies. Among them, YG type is suitable for drawing dies, YG6 and YG8 are suitable for small drawing dies, and YG15 is suitable for large drawing dies and stamping dies.

Cemented carbide is also used in the manufacture of measuring tools and wear-resistant parts, such as the measuring head of the micrometer, the top tip of the lathe, the guide plate of the finishing roll the centerless grinding machine, etc.

In recent years, steel-bonded cemented carbide has been widely used as a new tool and die material. After annealing, steel-bonded cemented carbide can be cut. After quenching and tempering, it has high hardness and wear resistance equivalent to cemented carbide, certain heat resistance, corrosion resistance, and oxidation resistance, and can also be welded. And forging, suitable for the manufacture of tools with complex shapes (such as twist drills, milling cutters, etc.), molds, and wear-resistant parts.
