Brass fasteners are used for their physical and aesthetic properties. Brass is utilized due to its high thermal conductivity and corrosion resistant properties, it is suitable for use in hot and cold environments, and resistant to water corrosion, making it a staple of industries such as heating and plumbing. Brass fasteners are largely non-magnetic (like any fastener, slight magnetic properties can develop during the manufacturing process) and resistant to tarnishing.

China's metal processing machine tool import volume and its changing trend from January 2010 to September 2011 In the first three quarters of 2011, China imported a total of 90,200 metal processing machine tools, an increase of 13.7% over the same period of 2010, 79,300 units; It was US$9.914 billion, an increase of 51.4% from US$6.547 billion in the same period of 2010; the average import unit price was US$10.99 million/unit, an increase of 33.21% over the same period of 2010 of US$82,500/unit. From January 2010 to September 2011, China's metal processing machine tool import volume chart According to statistics, in August, China imported 1909 CNC machine tools, a slight decrease of 0.05% from the previous month, down 7.33% year-on-year; the import value was 562 million US dollars, the chain ratio It increased by 15.7%, and also increased by 80.63% year-on-year; the unit price of imports was 294,400 US dollars/set. The chain increased by 15.76%, an increase of 94.91%. From January to August, China imported a total of 15,700 CNC machine tools, an increase of 43.6% year-on-year. The import value was about 3.301 billion US dollars, up 54.27% year-on-year. The average import price was US$21.23 million per unit, up 4.76% year-on-year.
In the first three quarters of China's CNC machine tool import volume price chart from January 2010 to July 2011, China's metal processing machine tool imports increased by 51% year-on-year; meanwhile, the import value of CNC machine tools in the first eight months increased by 54% year-on-year, reflecting China's The demand for medium and high-end products in the machine tool market has increased significantly, which also reflects the inadequacies in the domestic and high-end products in terms of technology and industrialization. In the first three quarters, the average unit price of China's metal processing machine tools increased by 33.21%. The main reason is that the machine tool with a relatively high proportion in the import of metal processing machine tools, such as horizontal lathes, other grinding machines, tool grinding machines, ultrasonic machining machines, punching machines , forging or stamping machine tools, has a higher unit price increase. This also shows that the product structure adjustment of the machine tool industry is not ideal, and the goal of replacing imports is not well achieved.
Brass fasteners are suited for some marine environments, including brackish water and slow current sea water; brass in this environment develops a protective green coating. Brass fasteners are also commonly used with wood applications, as the golden coloring blends well with the tan wood. Brass is a softer metal and must be used with care, always drilling pilot holes and using driver bits that fit the head of the screw precisely to prevent stripping. Brass Bolts also require a pilot hole be driven before installtion.
On October 13, the latest statistics released by China's customs showed that in September 2011, China imported 9,863 metal processing machine tools , down 10.98% from 11078 units in the previous month, and 13.3 fewer than the 11376 units in September 2010. %; the import value was about 1.282 billion US dollars, down 7.19% from the previous month's 1.381 billion US dollars, but still increased by 33.2% compared with September 964 million US dollars; the average import price was 130,000 US dollars / Taiwan, compared with last month The US$124,700/unit increased by 4.24%, a substantial increase of 53.64% from September's US$84,600/unit.
