5 Common Metal Stamping Parts and Where They’re Used
Metal stamping transforms flat sheets into high-strength parts with perfect repeatability. At Prime, our 12 stamping presses produce over 2 million parts monthly for global industries.
The five most stamped metal parts are brackets (50% automotive use), electrical contacts (gold/nickel-plated), shielding cans (EMI protection), washers (M6-M24 sizes), and hinges (300,000-cycle durability). Each serves critical functions in electronics, vehicles, and machinery.
Let’s examine these workhorse components:
1. Mounting Brackets – The Automotive Backbone
Every car contains 120-200 stamped brackets for structural support.
**Prime’s stamping data shows:
- 2mm cold-rolled steel most common
- ±0.1mm tolerance ensures proper fit
- Powder coating prevents rust
Used for engine mounts, seat frames, and sensor holders**
Bracket Specifications
| Feature | Typical Value |
|---|---|
| Thickness | 1.5–4mm |
| Material | SPCC steel, 5052 aluminum |
| Finish | Zinc plating, powder coat |
| Production Speed | 800–1,200 pieces/hour |
2. Electrical Contacts – Powering Modern Devices
Precision-stamped contacts ensure reliable current flow.
**Our medical device clients require:
- 0.3mm beryllium copper springs
- Gold plating (0.5–1.5μm) for conductivity
- 10-million-cycle durability
Found in switches, relays, and battery terminals**
Contact Material Comparison
| Material | Conductivity | Cost | Common Use |
|---|---|---|---|
| C1100 Copper | 100% IACS | $$ | Home appliances |
| Beryllium Copper | 22% IACS | $$$$ | Aerospace connectors |
| Nickel Silver | 15% IACS | $$$ | Audio equipment |
3. EMI Shielding Cans – Protecting Electronics
These Faraday cages block electromagnetic interference.
**Smartphone manufacturers demand:
- 0.2mm stainless steel cases
- Laser-cut ventilation slots
- Snap-fit designs for easy assembly
Critical for 5G modules and IoT devices**
4. Washers – The Unsung Heroes
Stampings prevent bolt loosening and surface damage.
**Industrial equipment uses:
- M6-M24 standard sizes
- Hardened 65Mn steel for heavy loads
- Blue-dyed lock washers
Essential in construction and machinery**
Washer Types Breakdown
| Type | Function | Thickness |
|---|---|---|
| Flat | Distribute load | 0.5–3mm |
| Spring | Prevent loosening | 0.8–2mm |
| Shoulder | Align components | 1–5mm |
5. Hinges – Smooth Motion, Every Time
Stamped hinges outperform cast versions in cost and weight.
**Our best-selling designs:
- 1.2mm 304 stainless steel
- Self-lubricating bushings
- 180° rotation without sagging
Used in industrial cabinets and medical devices**
Conclusion
From car frames to smartphones, these five stampings — brackets, contacts, shields, washers, and hinges — form hidden infrastructures across industries. Prime’s ISO-certified stamping lines deliver these components with <0.2% defect rates to 37 countries. Need durable, precision metal parts? We stamp success.
