China Suppliers Factory Precision Casting Pull Ring - Brass Electrical Fitting, 79mm x 96mm x 18mm
This is an electrical accessory, the name is pull ring.
Silicon Bronze is a kind of copper with good mechanical properties, corrosion resistance, processing performance, so it is widely used in the machinery manufacturing industry, shipbuilding industry, power industry, construction industry.
The melting point of copper is high, need to strictly control the melting temperature, to avoid overheating or overcooling resulting in a decline in material properties.
Copper in the liquid state of the fluidity is better, but also easy to lead to uneven flow of liquid metal in the mould, the need to ensure that the material is fully filled with details of the mould through the design of a reasonable pouring system and pressure to ensure that the details of the mould.
Copper is susceptible to oxidation, it is necessary to reduce the impact of oxidation on the quality of castings through a reasonable design of the pouring system as well as the control of the pouring temperature and pouring speed.
