Technical procurement data
Standards, supply and inspection
C70250 Strips C70250 is a precipitation-strengthened copper-nickel-silicon alloy used where conductivity, strength and stress relaxation resistance must be balanced. Strip orders require precise temper, thickness and edge definitions because these govern stamping behaviour and connector performance.
| Material / grade | UNS C70250 copper-nickel-silicon alloy; temper is selected for the forming sequence and final strength requirement. |
|---|---|
| Product form | Strip |
| Standards and order reference | Material is supplied against UNS C70250 and the strip specification, temper and property limits stated in the purchase order. |
| Dimensions and tolerances | Thickness, width, coil inside diameter, coil weight, camber and edge condition are confirmed before production; slitting tolerance is quoted by width and temper. |
| Surface and supply condition | Clean rolled surface with slit, deburred or rounded edges; protective interleaving and moisture-resistant packing can be specified. |
| Inspection options | Chemistry, tensile/hardness, conductivity, thickness, width, camber and surface inspection according to the agreed control plan. |
| MTC and traceability | MTC/inspection certificate with lot traceability, measured properties and dimensional inspection results. |
| Typical applications | Electrical connectors, lead frames, spring contacts, relay parts and precision stamped electronic components. |
| RFQ checklist | Send the strip grade and standard, required dimensions and tolerance, quantity, surface/condition, inspection and certificate requirements, packing preference and delivery destination. |
Final compliance is defined by the purchase order, approved drawing and issued mill documentation. Availability is confirmed for each grade, size and production route.

Features & Benefits
- High Strength: Copper has excellent strength properties, which makes it ideal for use in high-stress applications such as springs, bearings, and other mechanical components.
- Good Corrosion Resistance: The presence of phosphorus in the alloy provides excellent corrosion resistance, making it suitable for use in environments where the material may be exposed to moisture or corrosive substances.
- Good Wear Resistance: Copper has good wear resistance, which means it can withstand abrasion and wear without deforming or breaking.
Good Electrical Conductivity: Copper has good electrical conductivity, making it ideal for use in electrical connectors and other applications where electrical conductivity is important.
Easy to Process: Copper can be easily cold worked or hot worked, making it easy to form into strips or other shapes. It can also be soldered and brazed, which makes it a versatile material for a range of applications.
