Comparison of materials used in curtain parts for stamping
Comparison of materials used in curtain parts for stamping:
Commonly used stamping materials for curtain parts include carbon steel, stainless steel, aluminum alloy, copper alloy, and composite materials. This article provides an in-depth comparison of the characteristics, advantages and disadvantages, and applicable scenarios of each material to help engineers and purchasing agents find the optimal solution:
1. Steel materials
| Material name | Features | Applicable parts | Common surface treatment methods |
|---|---|---|---|
| Cold-rolled steel sheets, hot-rolled steel sheets (SPCC, SPHC) | Low cost, high rigidity, easy to process, but requires rust prevention | Mounting bracket, pulley seat | Galvanized, painted |
| Hot-dip galvanized steel sheet (GI) | The surface has zinc layer, good corrosion resistance | Bracket, end cap | Can be used directly or repainted |
| Stainless steel (SUS301 / SUS304 / SUS430) | Strong corrosion resistance, good appearance, no painting required | High-end decorative parts, outdoor brackets | Polishing, brushing, electrolysis, passivation |
2. Aluminum and aluminum alloys
| Material name | Features | Applicable parts | Common surface treatment methods |
|---|---|---|---|
| Pure aluminum (1100) | Lightweight, corrosion-resistant, and easy to form | Decorative cover, end cap | Anodizing, painting |
| Aluminum alloy (6061, 5052) | Higher strength than pure aluminum and good formability | Pulley seat, frame decoration | Anodizing, electrophoresis, powder coating |
3. Copper and copper alloys
| Material name | Features | Applicable parts | Common surface treatment methods |
|---|---|---|---|
| Brass (C2680) | Good texture, good corrosion resistance, high cost | High-end decorative metal parts | Polishing, chrome plating, gold plating |
| Copper-nickel alloy | Stable gloss, not easy to change color | Decorative strips | Polishing, electroplating |
4. Plastic composite materials (special cases)
Although stamping is mostly done with metal, some parts use a metal + plastic composite structure, for example:
- The inner layer of the guide rail end cover is made of ABS or POM, and the outer shell is made of metal
- Pulley guards are made of PC or nylon
Different materials have their own advantages and limitations. Choosing the right material for curtain stamping parts can ensure that the product is stable and durable in various environments while taking into account cost and design requirements.
