CNC Metal Machining Materials
Selecting the right metal for CNC machining is critical to achieving optimal performance, cost-efficiency, and durability. XTJ Precision Mfg offers a wide range of metals tailored to your project requirements. Below are some of the key materials we work with:
Aluminum is a cost-effective, lightweight metal with excellent machinability and a high strength-to-weight ratio, ideal for precision CNC machining.
- AL6061-T6: Widely used for its excellent machinability, corrosion resistance, and affordability. Ideal for automotive, aerospace, and construction components.
- AL7075-T6: High-strength aluminum with superior fatigue resistance, perfect for high-stress aerospace and automotive parts.
- AL6082: Offers the highest strength in the 6000 series, with excellent corrosion resistance, suitable for defense and aerospace applications.
Stainless steel combines good machinability with corrosion resistance and strength, making it a versatile choice for CNC machining.
- SS304: Known for its formability and weldability, used in kitchen appliances, food handling equipment, and piping systems.
- SS303: Offers excellent corrosion resistance and durability, ideal for gears, shafts, and aircraft fittings.
- SS316: Features superior corrosion resistance due to molybdenum content, perfect for medical implants and aerospace components.
Titanium offers an exceptional strength-to-weight ratio and biocompatibility, making it ideal for medical devices and aerospace applications, though it is costly to machine.
Copper and its alloy, brass, are highly machinable metals with excellent thermal and electrical conductivity, ideal for electrical and plumbing applications.
- Copper: High conductivity makes it perfect for electrical components, though it is more expensive.
- Brass (H59): A copper-zinc alloy with high tensile strength and corrosion resistance, used in automotive, plumbing, and musical instruments.
Magnesium is lightweight and highly machinable, ideal for automotive and aerospace parts, but requires careful handling due to fire hazards.

Factors to Consider for CNC Metal Machining
Choosing the right metal for CNC machining impacts cost, performance, and production time. Here are key factors to consider:
Machining Time
Metals with high machinability, like aluminum, reduce machining time and costs. Complex part geometries increase machining time, impacting overall expenses.
Strength and Environmental Requirements
Select metals based on the part’s intended use. High-stress applications require strong metals like stainless steel or titanium, while lightweight applications may favor aluminum or magnesium.
Finishing and Post-Processing
XTJ offers extensive surface finishing options, including anodizing, powder coating, and polishing, to enhance aesthetics and remove machining marks. The choice of metal affects the finishing process and cost.
