The common materials used in CNC machining mainly include metal, plastic, composite materials, and special materials, specifically including aluminum alloy, stainless steel, carbon steel, copper, titanium alloy, ABS plastic, PC plastic, etc.
metal material
Aluminum alloy: 6061 (medium strength, corrosion-resistant), 7075 (high-strength, aerospace) 12
Stainless steel: 303 (easy cutting), 304 (universal type), 316 (corrosion-resistant), 17-4PH (high-strength) 23
• Carbon steel: 45 # steel (general structural component) 13
• Copper: Purple copper (good conductivity), brass (easy to process) 12
• Titanium alloy: Grade 5 (Ti-6Al-4V, high strength), Grade 23 (medical grade) 2
plastic material
General engineering plastics: ABS (low cost, good toughness), PC (transparent and impact resistant) 4
• High performance plastics: POM (wear-resistant and self-lubricating), PEEK (high temperature and high strength), PTFE (corrosion-resistant and non stick) 4
composite material
CFRP (Carbon Fiber Reinforced Plastic, Lightweight and High Strength)
GFRP (Glass Fiber Reinforced Plastic, Corrosion Resistant) 5
special materials
Magnesium alloy (lightweight but flammable)
• Wood/stone/leather (non-standard customized scene)
