1.Copper-Based Investment Castings | Brass & Bronze Castings
Welleshaft offers Copper Based Casting Services for precision parts with tight tolerances and complex shapes. Whether you need brass investment casting for plumbing or bronze alloy castings for engine components, we deliver consistent performance with minimal material waste.
This guide covers the properties, applications, and advantages of brass, bronze, and copper alloy castings. You’ll also find tips on choosing the right copper alloy to match your specific production needs.
2.Why Use Copper-Based Investment Casting?
Copper Based Casting Services are ideal when you need excellent thermal conductivity, smooth machinability, and corrosion resistance. Unlike CNC machining or forging—which often leads to excess scrap and longer cycle times—investment casting keeps material waste low and shapes closer to final form.
At Welleshaft, we deliver near-net-shape copper castings through efficient processes designed for both short runs and high-volume production. Whether you’re dealing with intricate geometries or tight dimensions, our casting services help reduce machining time and speed up delivery.
Advantages of Copper Investment Casting
- Less scrap left behind
- Handles tight and tricky shapes
- Cheaper than machining or forging
- Clean, smooth finishes
3.Brass Investment Casting
Brass is a brass-based alloy made from copper and zinc. Known for its golden look and good machinability, it sees wide use in plumbing, hardware, and auto parts.
（1）Key Applications
- Brass casting parts for automotive suppliers
- Lead-free types like Enviro Brass for water use
- Handles, valves, and fittings
- Brass investment cast parts for heavy machines
（2）Benefits of Brass Investment Casting
- Polishes up well
- Works in tight-fit applications like aerospace
- Machines easily, even on complex parts
4.Bronze Investment Casting
（1）What is bronze investment casting used for?
Bronze mixes copper with tin, lead, or other stuff. You’ll see it in bearings, bushings, and marine parts. It fits where durability’s needed.
（2）Common Bronze Alloys and Their Uses
| Alloy | Description & Applications |
| CA95400 | Gears, pumps |
| CA95500 | Bushings, heavy loads |
| CA95800 | Saltwater hardware |
| CA86300 | Bearing blocks, gear sets |
| CA86500 | Parts needing extra strength |
（3）Benefits of Bronze Investment Casting
- Performs well based on alloy blend
- Perfect for tooling and die-cast needs
- Seen in aerospace-grade bronze investment castings and OEM engine parts
- Used in automotive-grade bronze parts too
- Great for industrial bronze metal components
（4）Elements and Their Effects
- Tin: Brings up strength
- Lead: Helps lubrication but cuts strength
- Aluminum/Manganese: Fights rust, adds toughness
5.Beryllium Copper and Silicon Copper Castings
（1）Beryllium Copper Castings
Beryllium-copper is a high-strength copper alloy. It’s solid in aerospace and military uses.
- Strong and light
- Doesn’t spark
- Machines nicely
Great for:
- Defense-grade copper castings
- Precision brass aerospace parts
- Custom copper alloy parts for military
（2）Silicon Copper Alloy Castings
Silicon bronze (like CA87600) stands up to rust and follows eco rules.
- Swaps out leaded bronze in plumbing
- Good for mid-strength jobs with clean finish
6.Common Copper Alloys Used in Investment Casting
| Alloy | Applications |
| CA95200 | Landing gear, marine parts |
| CA95300 | High heat resistance |
| CA95400 | Gears, pumps |
| CA95500 | Bushings, gear arms |
| CA95800 | Sea-water fittings |
| CA86300 | Bearings, gear trains |
| CA86400 | Propellers, lever arms |
| CA86500 | High-load structural parts |
7.People Also Ask
-
What is bronze casting in a sentence?
Bronze casting means melting bronze alloy metal and pouring it into a mold to make durable, detailed parts.
-
What are the differences between brass-based and bronze alloy castings?
Brass is smoother and easy to cut, bronze is tougher and holds up better. Both work in copper casting jobs, but for different needs.
-
How copper casting works for industrial parts?
Pour molten cast copper into a ceramic mold. Once cooled, crack the mold open. You get a near-final shape, ready with just a little cleanup—good for industrial bronze alloy parts.
-
When to use brass investment casting in manufacturing?
Use brass investment casting when you want nice looks, smooth surface, or corrosion resistance. Best for plumbing, auto trim, or electronics.
-
What are the benefits of using bronze alloy metal in casting?
Bronze alloy metal gives great wear life and handles stress well. It fits tool parts, marine gear, and OEM components.
-
What are the advantages of cast copper vs forged copper?
Cast copper shapes complex parts faster and for less money. Forged copper is stronger, but it takes more machining.
