Detailed Explanation of Common Materials Used in Sheet Metal Processing
Material selection in sheet metal processing directly impacts product strength, corrosion resistance, machinability, and cost. Below is a comprehensive breakdown of common metal, along with special-purpose materials for niche applications.
I.SHeet Metal fabrication Materials
1. Carbon Steel sheet fabrication(Cold-Rolled/Hot-Rolled)
Representative Grades:
- SPCC (Cold-Rolled), SPHC (Hot-Rolled), Q235, DC01
Characteristics:
- Cold-Rolled Steel(SPCC): Smooth surface, tight thickness tolerance (±0.05mm), ideal for stamping and bending.
- Hot-Rolled Steel(SPHC): Thick oxide layer requires pickling before use; lower cost but poorer precision.
- Yield Strength Steel: DC01 (cold-rolled): 180–280 MPa; Q235 (hot-rolled): 235 MPa.
Applications:
- Cold-Rolled Steel: Electrical cabinets, elevator cars, automotive body panels.
- Hot-Rolled Steel: Building structural components, mechanical brackets (where surface finish is less critical).
Key Considerations:
- Requires anti-rust treatment (e.g., galvanizing, painting) to prevent corrosion.
- Springback must be controlled during bending (pre-bending or die compensation recommended).
2. Stainless Steel sheet
Representative Grades:
- 304 (06Cr19Ni10), 316L (022Cr17Ni12Mo2), 430 (10Cr17)
Characteristics:
- 304: Excellent corrosion resistance for general environments (e.g., food machinery, kitchenware).
- 316L: Contains molybdenum (2.0–3.0%), resistant to seawater and chloride corrosion (chemical, marine applications).
- 430: Ferritic stainless steel; lower cost but inferior corrosion resistance (used for indoor decor).
Machining Challenges:
- Laser cutting requires nitrogen shielding to prevent oxidation discoloration.
- Minimum bend radius ≥1.5× plate thickness to avoid cracking.
Applications:
- 304: Medical devices, elevator doors, subway handrails.
- 316L: Offshore platforms, seawater desalination equipment.
3. Aluminum Alloys sheet
Representative Grades:
- 5052 (Al-Mg), 6061 (Al-Mg-Si), 1060 (Pure Aluminum)
Characteristics:
- 5052: High strength (yield strength ≥195 MPa), good corrosion resistance, weldable.
- 6061: Heat-treatable; higher strength (T6 state yield strength ≥240 MPa) for structural parts.
- 1060: ≥99.6% purity; excellent electrical conductivity but low strength (used for heat sinks).
Sheet metal Fabrication Advantages:
- Laser cutting is twice as fast as steel.
- Minimal springback during bending, but die clearance should be ~0.8× plate thickness.
Applications:
- 5052: Automotive fuel tanks, ship decks.
- 6061: Drone frames, bicycle frames.
4. Copper & Copper Alloys sheet
Representative Grades:
- T2 (Pure Copper), H62 (Brass), QSn6.5-0.1 (Tin Bronze)
Characteristics:
- T2: Superior electrical conductivity (≥58 MS/m) for conductive components.
- H62: 62% Cu content; high strength (yield strength ≥200 MPa) and moderate corrosion resistance.
- QSn6.5-0.1: Contains 6.5% Sn; excellent wear resistance for bearings and gears.
Sheet metal brication Challenges:
- High thermal conductivity requires high laser power (≥3 kW) and high auxiliary gas pressure for cutting.
- Preheating to 150–200°C is needed to prevent cracking during bending.
Applications:
- T2: Transformer terminals, busbars.
- H62: Locks, valve components.
5. Coated Steels USED IN CUSTOM SHEET METAL FABRICATION
Material Types:
- Electro-Galvanized (SECC): Zinc layer 3–20 μm thick; better corrosion resistance than cold-rolled steel (indoor appliances).
- Hot-Dip Galvanized (SGCC): Zinc layer 45–300 μm thick; extreme corrosion resistance (outdoor structures).
- Galvalume (GL): Aluminum-zinc alloy coating; 2–6× more corrosion-resistant than hot-dip galvanized (building roofs).
Key Considerations:
- Welding produces zinc vapor; ensure ventilation or use laser welding to reduce fumes.
- Avoid coating flaking during bending (die radius ≥0.5 mm).
II. Special-Purpose Materials
1. Titanium Alloys USED IN METAL FABRICATION SERVICE
Representative Grades:
- TA15 (Ti-6Al-2Zr-1Mo-1V), TC4 (Ti-6Al-4V)
Characteristics:
- Density: 4.5 g/cm³ (60% of steel); high strength (TC4 yield strength ≥825 MPa).
- Withstands high temperatures (retains strength at 600°C); seawater-resistant.
Applications:
- Aircraft engine blades, marine propellers, medical implants (artificial joints).
Machining Considerations:
- Laser cutting requires ≥6 kW power with argon shielding.
- Preheating to 300–400°C and lubricated dies are needed for bending.
2. Magnesium Alloys
Representative Grades:
- AZ31B (Mg-3Al-1Zn), AZ91D (Mg-9Al-1Zn)
Characteristics:
- Density: 1.74 g/cm³ (66% of aluminum); high specific strength.
- Excellent damping properties (vibration absorption).
Applications:
- Laptop housings, automotive wheels, drone frames.
Machining Challenges:
- Prone to oxidation fires; cutting requires CO₂+O₂ protective gas.
- Controlled bending at 150–200°C to minimize springback.
III. Material Selection Principles
1. Performance Matching
- Corrosion Resistance: Choose 316L stainless steel or Galvalume for marine environments.
- Strength: Opt for 6061-T6 aluminum or Q345 carbon steel for structural parts.
- Lightweighting: Use titanium alloys or CFRP in aerospace.
2. Cost Optimization
- For high-volume production, hot-rolled steel is 20% cheaper than cold-rolled.
- Replace 304 stainless steel with 430 where surface finish is less critical.
