Q: What are the core application areas of SPCC coils?
A: Home appliances (refrigerator/washing machine housings), electronics (chassis/brackets), automotive (interior parts/small stamped parts), hardware (furniture accessories/shelves), instrument housings.
Q: What cold working processes is SPCC suitable for?
A: Stamping, bending, stretching, flanging, shearing; not suitable for high-strength structural parts (SPCC-1 hard or upgraded to SPCE can be used).
Q: Why is SPCC-A or S grade preferred for deep-drawn parts?
A: Annealed/standard tempered elongation ≥34%, better plasticity, reducing the risk of cracking and springback.
Q: Precautions for welding SPCC?
A: Use low-carbon welding wire (such as ER70S-6), control the heat input to avoid overheating; for thin materials (<1.2mm), use argon arc welding or resistance welding to prevent burn-through.
Q: Can SPCC be galvanized/aluminized zinc plated?
A: Yes, but surface cleaning (degreasing/pickling) is required first. It is compatible with hot-dip galvanizing or electro-galvanizing lines.
