Product Description

This is a part used in sea vessel components, sea and fresh water heat exchanger system, the name is end cap.

Adopting ZCuSn12 as the material, tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage, which can be used to produce castings with complex shapes and clear contours; tin bronze is very corrosion-resistant in the atmosphere, seawater, freshwater and steam, so it is widely used in steam boilers and seagoing ship parts.

Product Features

  • In the field of silicone sol investment casting, which is considered a large product, and the product has the sealing requirements, so for the casting process control requirements are high.
  • Compared with the casting of steel, copper melting point is relatively low, liquefied when the mobility is relatively good, but also easy to lead to liquid metal in the mold uneven flow.
  • Copper in the casting process is easy to produce oxidation problems.
The above characteristics lead to the low qualification rate of copper precision casting.

Frequently Asked Questions

Q1: What is the main application of this end cap?
A1: This end cap is specifically designed for use in sea vessel components, as well as sea and fresh water heat exchanger systems.
Q2: Why is ZCuSn12 tin bronze selected as the material?
A2: ZCuSn12 tin bronze is chosen because it has the smallest casting shrinkage among non-ferrous metal alloys, allowing the production of complex shapes with clear contours. Additionally, it offers exceptional corrosion resistance in atmosphere, seawater, freshwater, and steam.
Q3: What makes the casting process of this copper end cap challenging?
A3: The challenges arise from strict sealing requirements, the relatively low melting point of copper which leads to high mobility and potential uneven flow in the mold, and the high susceptibility of copper to oxidation during the casting process.
Q4: How long has this product been in stable production?
A4: This product has been successfully developed and in continuous mass production since 2012, ensuring a stable and reliable supply.
Q5: Do you provide machining services for these cast components?
A5: Yes, we provide fully integrated services that cover everything from the initial precision casting process to final machining, ensuring high efficiency and quality control.
