Analysis on technical level and technical characteristics of bimetal band saw blade industry
(1) High speed steel bimetal band saw blade
High speed steel bimetallic band saw blades are widely used in various industries such as machining, steel, automobile and parts, non-ferrous metals and so on. Related to developed countries, China's high-speed steel bimetallic band saw blade started late, but its development speed is fast.
The technical level of China's high-speed steel bimetallic band saw blade enterprises presents an obvious "pyramid" pattern. In the consumption category of band saw blades, saw blades with a width of 27mm ~ 41mm belong to ordinary products with low technical content; The saw blade with width less than 27mm belongs to ultra narrow band, which is mainly used for sawing with high precision; The saw blade with width greater than 41mm belongs to wide band, which is mainly used for special sawing; The consumption and processing of ultra narrow band and broadband are difficult, and the technical content is high. At present, most domestic small and medium-sized consumer manufacturers can only consume a few standard saw blades within the range of 27mm ~ 41mm; Some enterprises can consume products of all specifications within the range of 27mm ~ 41mm; A few leading enterprises in the industry have the ability of ultra narrow band and broadband consumption.

(2) Carbide band saw blade
Compared with high-speed steel bimetallic band saw blade, cemented carbide band saw blade has higher sawtooth hardness and cutting efficiency. It is mainly used for cutting superhard alloys, such as superalloys and titanium alloys used in aerospace, and duplex stainless steel required in nuclear power equipment. Before 2009, China did not have the consumption technology of cemented carbide band saw blades, and the local market was monopolized by foreign enterprises. After 2009, China successfully developed the first consumption line of cemented carbide band saw blade, and completed the zero breaking of domestic cemented carbide band saw blade.
