- Applications: DIY repairs, electronics, decorative metalwork
Universal Flat Washer Gasket
This ultra-thin, high-precision flat washer functions as a gasket and shim for tight tolerances in mechanical assemblies. Made from SUS304 stainless steel, the gasket offers abrasion resistance and smooth operation, with reduced magnetic properties typical of this grade. Its compact dimensions make it ideal for precise adjustments in machinery, electronics housings, and cabinetry hardware.
- Material: SUS304 stainless steel
- Precision: Ultrathin profile for fine adjustments
- Applications: Machinery assemblies, electronics, cabinetry
Extended Tension Spring Wire
The Extended Tension Spring Wire set includes multiple diameters (0.2 to 0.6 mm) with a stainless steel composition. Each piece features dual hook ends and short lengths suitable for small tensioning tasks, hardware adjustments, and fastener recovery systems. The robust construction provides dependable spring action across a range of working environments, with corrosion resistance typical of 304 stainless steel.
- Material: 304 stainless steel
- Diameter options: 0.2–0.6 mm
- Length: 15–60 mm; Outer diameter options include 2–6 mm
Pure T2 Copper Sheets (Discs)
These round discs made from T2 copper are ideal for electrical repairs, crafts, and EMI shielding. The discs facilitate easy welding and brazing thanks to smooth surfaces and excellent conductivity. High plasticity and ductility enable shaping through cold rolling, hot rolling, or wire drawing. Their round form supports quick, precise replacements and custom components in electronics and metal craft.
- Material: T2 copper
- Shapes: Round discs with 0.3 mm thickness
- Applications: Electrical repairs, EMI shielding, crafts
Buying Guide: Key Purchase Considerations
Choosing copper and metal components requires evaluating material properties, fabrication needs, and end-use conditions. Consider these perspectives to ensure you select fit-for-purpose items.
- Material quality: Pure copper offers superior electrical and thermal performance but can be softer; T2 copper balances conductivity with formability. Stainless steel provides strength, corrosion resistance, and precise shimming.
- Thickness and diameter: For sheets, thickness affects flexibility and electrical resistance. For washers and discs, diameter and inner bore (if applicable) determine compatibility with fasteners and assemblies.
- Machinability and processing: Look for sheets and foils that support cutting, stamping, bending, welding, and brazing. Ensure the chosen parts meet your production or repair workflow.
- Corrosion and environmental exposure: Stainless steel resists rust, while copper surfaces may patina; consider coatings or EMI shielding needs for electronics.
- Size and tolerances: Ultra-thin gaskets and shims require tight tolerances. Verify precision specifications to avoid assembly gaps or misfits.
Applications span electrical repairs, DIY crafts, electronics enclosures, and mechanical assemblies. The selected products emphasize versatility, conductive performance, and ease of fabrication, supporting both hobbyists and professionals in achieving durable results.
