The bimetal band saw blade is a high-tech product processed by a series of processes such as electron beam or laser welding, machining, and heat treatment, which uses two different kinds of steels (high-speed steel and backed steel). It is an industrial consumable that is used for metal cutting with a band sawing machine. Band sawing is one of the mainstream cutting methods currently used. The range of cutting objects is extremely wide, including all kinds of steel and non-ferrous metals such as copper and aluminum.

　　At the end of 1985, China produced the first batch of domestically-made bi-metal band saw blades, which opened the beginning of China's bi-metal band saw blade industry. After nearly 30 years of development, the bi-metal band saw blade industry in China has experienced the glorious history of zero-based local brands from scratch, gradually replacing imported brands, and achieving volume export.

　　At present, the local brands of bi-metal band saw blades are mainly concentrated in Hunan, Liaoning and Zhejiang provinces, among which the representative ones are: Hunan Taijia New Material Technology Co., Ltd., Hunan Tiancheng Saw Co., Ltd., and Liaoning Benxi Tools. Group Co., Ltd., Benxi Shuangjin Saw Co., Ltd., Dalian Shuangjin Saw Co., Ltd. and Dalian Special Steel Products Co., Ltd., and Zhejiang manufacturers are mainly small-sized enterprises.

　　Bimetal band saw blades can be divided into high-speed steel bi-metal band saw blades and hard alloy band saw blades according to the material selection and production process. The former is a bimetal band saw blade obtained by welding two kinds of alloy steels using a laser or electron beam welding process, which is processed by tooth milling, tooth splitting, heat treatment, and the like. Backing materials mainly use spring steel, and tooth materials mainly use high speed alloys. steel. The latter mainly uses cemented carbide as a tooth material. Due to the large difference in material technology, the price of carbide band saw blades is 7 to 9 times that of high-speed steel band saw blades.

　　At this stage, high-speed steel bi-metal band saw blades are the mainstream products of domestic double metal band saw blades. Due to the relatively expensive price and relatively short development history, the scale of production and sales of cemented carbide band saw blades is still far lower than that of high-speed steel bi-metal band saw blades.

　　In the past 10 years, the vigorous investment in national economic construction and the rapid development of the national economy have provided strong impetus for the development of the bi-metal band saw blade market in China. As the current mainstream product of the domestic double metal band saw blade industry, the market scale of high speed steel bimetal band saw blades has also achieved rapid expansion. In 2006, the domestic market for high-speed steel bi-metal band saw blades was 18.47 million meters, which reached 38.84 million meters in 2010.

　　From 2006 to 2011, the domestic double metal band saw blade industry was in a period of rapid development, and the market sales maintained a relatively rapid growth. In 2012, due to the impact of the international financial crisis and the decline in the domestic manufacturing climate index, downstream industry demand has decreased, and sales have declined slightly. In 2013, the downstream industry picked up slightly, and sales of the bi-metal band saw blade saw a rebound. The market scale of high-speed steel band saw blades for 2011 to 2013 was 48 million meters, 46 million meters and 50 million meters respectively.

　　Under the premise of no major changes in the domestic economic fundamentals and the status quo of the industry, it is expected that the bi-metal band saw blade industry will continue to maintain a growth rate of approximately 15% in the next 3 to 5 years. It is expected that sales in 2018 will reach 84 million meters, according to 45 The average price of yuan/meter is estimated to total 3.78 billion yuan.

　　With the further promotion of urbanization and continuous development of the manufacturing industry, the domestic market for double-metal band saw blades will continue to grow. At the same time, market competition will also become increasingly fierce. In the next few years, there will be a trend of concentration of market shares to dominant companies, and the market share of local brands will increase further.
