Generally suitable for metal band sawing machines, the sawing band and the teeth are not the same material, so it is called bimetal band saw blade! Should be suitable for sawing all kinds of steel so the hardness of the tip is better

　　The material of the bimetal band saw blade is mainly formed by welding two kinds of metals such as a tooth portion and a back with an electron beam (or laser). Band Saw Blade Gear Material: In the initial stage, the bi-metal band saw blade materials were M2 and M4, and their hardness was gradually reduced when they were too low. Nowadays, common tooth materials are generally used in the M42. Alloy steel is the main one, and there is a high-tungsten cobalt alloy tool steel, and there are more advanced toothed materials and M51. Band saw blade back material: Due to the different standards of countries in the world, the grades of their materials are also expressed in different ways, which are mainly divided into: X32, B318, RM80, B313, D6A, 505 and so on. But these are all part of the 46CrNiMoVA material family.

　　The band saw blade tooth material is characterized by high hardness, high wear resistance, and high red hardness (no matter how hard it is to maintain its hardness in a high-temperature environment). The band saw blade M42 tooth material contains cobalt up to 8 More than % is an ideal alloy high speed steel material. The back material is very resistant to fatigue.

　　Bi-metal band saw blades are widely used: The main purpose of bi-metal band saw blades is to cut ordinary black metal, such as cast iron, cast steel, rolled round steel, square steel, pipe, steel; also can be used to cut alloy tool steel, alloy structure Steel, die steel, bearing steel, stainless steel, hard, sticky metal; can also cut copper, aluminum and other non-ferrous metals. If you want to choose a reasonable and reasonable tooth (jumping), you can use it to cut frozen fish, frozen meat, and hard frozen products. After some special processing, a large amount of bi-metal band saw blades are also commonly used to cut mahogany and beech wood. , iron pear wood and other hard expensive wood.

　　Commonly used are divided into fine teeth, medium teeth, large teeth. The best way to distinguish is to use a caliper to measure the distance between two adjacent larger tips, measure in millimeters, divide by 25.4 (inches in inches), and measure the distance between two smaller tips or divide by 25.4; There is a ratio between these two figures, which is the legendary 2/3 tooth, 3/4 tooth, and 4/6 tooth saw blade. Or 0.75/1.25, 1.0/1.6 and so on. The tooth shape also has the angle distinction, 0°, 6°, 10° and so on. There are also tensile tooth saw blades, T-shaped tooth saw blades, etc. Each manufacturer's product has different characteristics.
