China Suppliers Factory: Brass Precision Castings for Inlet and Outlet End Caps in Marine Heat Exchanger Systems
Product Description
This is a part used in the sea ship parts, sea fresh water heat exchanger system, the name is called inlet and outlet end cap.
ZCuZn16Si4 is a casting copper alloy material with high mechanical properties and good corrosion resistance, good casting performance, high mobility, widely used in pipe fittings working in contact with seawater, as well as pumps, impellers, plugs and castings working in air, fresh water, oil, fuel, as well as working pressure of 4.5MPa and in steam at 250 ℃ or less.
Product Features
In the field of silicone sol precision 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.
Product History
From the receipt of the project, our technical team worked night and day to overcome the difficulties, and through continuous optimization of the pouring system, control of the pouring temperature and flow rate, the project was finally developed successfully and formed mass production.
This product has been in mass production since 2013, and has been in stable supply for 11 years, which has given us a lot of experience in the field of copper casting.
Our company has a strong technical development team, with the development of precision casting of various shaped parts in the field of ability, and to provide integrated services from casting to machining, striving for excellence, to provide customers with efficient, high-quality products and services has always been our adhering to the concept.

Frequently Asked Questions
Q: What is the material used for this inlet and outlet end cap?
The end cap is made of ZCuZn16Si4 casting copper alloy, which features high mechanical properties, good corrosion resistance, high mobility, and excellent casting performance.
Q: Under what working conditions can this end cap be applied?
It is designed for sea ship parts and sea fresh water heat exchanger systems. It functions reliably in contact with seawater, air, fresh water, oil, fuel, and steam at temperatures up to 250 ℃ with a working pressure of up to 4.5MPa.
Q: What are the main challenges in casting copper alloy parts?
Copper has a lower melting point than steel, leading to high mobility when liquefied, which can cause uneven flow inside the mold. Additionally, copper is highly susceptible to oxidation during the casting process, which typically lowers the qualification rate of precision castings.
Q: How did your team successfully overcome the casting difficulties of ZCuZn16Si4?
Our technical team continuously optimized the pouring system and strictly controlled the pouring temperature and flow rate to successfully achieve stable mass production.
Q: Do you provide machining services in addition to precision casting?
Yes, we provide integrated services from precision casting to machining, specializing in the development of various complex and shaped parts.
Q: How long has this product been in stable production?
This product has been in stable mass production and continuous supply since 2013, representing over 11 years of proven manufacturing experience.
