"How do I prevent work hardening in Stainless 304?"
Hardness, strength-to-weight ratio, and ultimate strength dictate the part's performance in service.
Affects production time and cost. Difficult materials can impose equipment constraints that overwhelm productivity.
Essential for performance. Determines if a material maintains strength at moderate or high temperatures.
How the material holds its size and shape, crucial for achieving and maintaining specific tolerances.
Thermal expansion and elasticity affect achievable tolerances. Brittle materials may need slower feeds.
A primary economic driver. E.g., Aluminum requires less machining time than Titanium, saving costs.
The right choice achieves a balance between machinability, availability, and performance to reduce production costs without sacrificing quality.
Selecting a cheaper but less serviceable material saves cost initially but risks part failure and costly redesigns later.
'Easier' materials simplify manufacturing but may lack utility. Difficult materials increase tool wear. (e.g., 360 Brass is excellent for chip breaking).
Softer materials risk deformation under load, while brittle materials may need significantly slower feeds to maintain accuracy.
| Industry | Key Priorities | Example Materials |
|---|---|---|
|
Aerospace
|
Extreme weight limits, high strength-to-weight ratio, strict regulatory compliance (AS9100). | Aluminum alloys (6061, 7075), Titanium (Grade 5), Superalloys, PEEK. |
|
Medical Devices
|
Biocompatibility, sterility, micron-level precision, regulatory compliance (ISO 13485). | Titanium alloys (implants), Stainless Steel (tools), medical-grade plastics. |
|
Automotive
|
Durability, moderated cost, precision, repeatability for safety-critical components. | Aluminum alloys, Magnesium, Composites. |
|
Electronics
|
Precision, light weight, thermal management, aesthetic finish. | Aluminum, Magnesium, Copper (heatsinks), ABS, Polycarbonate. |
Weight is key. Grade 5 Titanium (Ti-6Al-4V) is standard due to its outstanding strength-to-weight ratio and corrosion resistance, despite being harder to machine than Grade 2 Titanium.
Conductivity is priority. Copper Alloy 101 or 110 is chosen for excellent electrical/thermal conductivity, despite machining challenges like producing "gummy" chips.
