Basic characteristics |
This is flange bronze bushing with graphite, which Combined with the wear resistance of copper alloy and solid self-lubricating properties of the lubricant to use in the process of maintaining without refueling. Products are widely used in high-contained, intermittent or swing movement, such as steam locomotive production lines, turbine and reservoirs work / accident doors, plastic machinery. According to the conditions, can provide various types of copper alloy. 1 High temperature resistance: The melting point of the graphite bearing is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after the ultra-high temperature arc ignition, the weight loss and the coefficient of thermal expansion are very small. The strength of graphite increases with the increase of temperature. At 2000 ℃, the strength of graphite doubles. 2 Conductivity and thermal conductivity: the conductivity of graphite bearing is 100 times higher than that of general non-metallic ore. The thermal conductivity is higher than that of steel, iron, lead and other metal materials. 3 Lubricity: the lubricity of graphite bearing depends on the size of graphite flake. The larger the flake, the smaller the friction coefficient and the better the lubricity. |
