The alloy guide plate is an alloy material made of a hard compound of refractory metal and bonding metal through powder metallurgy. This alloy has a series of excellent properties such as high hardness, good wear resistance, good strength and toughness, good heat resistance and corrosion resistance, especially high hardness and wear resistance, which remain basically unchanged even at 500℃ .

Alloy guide plates are widely used as tool materials such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and also for cutting refractory steel and stainless steel. , High manganese steel, etc., tool steel and other difficult-to-process materials. At present, the hardness of alloy guide plates is hundreds of times that of carbon steel. The main reason is that the alloy guide plate is composed of two or more metal elements (or metal and non-metal elements), which has the characteristics of metal. Steel is an alloy composed of iron and carbon. The use of ancient bronze (alloy of copper and tin) can be traced back to the very early days of the use of alloys. The structure of the alloy guide plate is much more complicated than that of pure metal. According to the interaction between the constituent elements in the alloy, the alloy can generally be divided into three structural types: metal solid solution formed by mutual dissolution. Chemically interacting to form metal compounds. It does not form a mechanical mixture chemically.

In the mechanical mixture, the two components of the alloy can neither dissolve with each other nor react with each other to form a solid compound, and in the mechanical mixture, each phase still maintains its original crystal lattice and properties. The properties of the mechanical mixture are between the properties of the constituent phases. Most of the alloy guide plates in the industry are composed of a mixture of steel, cast iron and aluminum alloy.
