Copper Alloy Selection Guide
C011
Our most popular alloy, C011 is an industry benchmark for permanent mold construction. C011 is defined by the following characteristics:
| Alloy Group | Alloy | Specification | Nominal Chemical Composition | Yield Strength (psi x 10^3) | Tensile Strength (psi x 10^3) | Elongation % 2" | Brinell Hardness 10 mm/500kg | Modulus of Elasticity (psi x 10^6) | Electrical Conductivity % IACS | Description |
| High Conductivity Copper | C011 | High Conductivity Copper | Cu | 5.6 | 15 | 25 | 35 | 17.75 | >=91 | Very good electrical conductivity; due to its technological properties, this is an alloy for complicated castings; material has limited weldability. |
C030
Our C030 alloy is comprised of copper-nickel-silicon. Its characteristics are as follows:
| Alloy Group | Alloy | Specification | Nominal Chemical Composition | Yield Strength (psi x 10^3) | Tensile Strength (psi x 10^3) | Elongation % 2" | Brinell Hardness 10 mm/500kg | Modulus of Elasticity (psi x 10^6) | Electrical Conductivity % IACS | Description |
| High Conductivity Copper | C030 | Copper-Nickel-Silicon | Cu-Ni-Si | 48.6 | 63.9 | 12 | 135 | 17.5 | 39.6 | Hard and wear-resistant special copper alloy with relatively high conductivity; especially suited for highly demanding current-carrying parts in switch gear and wire clamps; very good resistance to atmospheric influence; no tendency toward stress corrosion. |
C010
Our C010 alloy is practically pure copper with excellent electrical conductivity traits. Its characteristics are as follows:
| Alloy Group | Alloy | Specification | Nominal Chemical Composition | Yield Strength (psi x 10^3) | Tensile Strength (psi x 10^3) | Elongation % 2" | Brinell Hardness 10 mm/500kg | Modulus of Elasticity (psi x 10^6) | Electrical Conductivity % IACS | Description |
| High Conductivity Copper | C010 | High Conductivity Copper | Cu | 5.6 | 21.2 | 25 | 35 | 17.75 | >=86 | Practically pure copper with the properties of annealed electrolytic copper; excellent conductivity for electrical and thermal uses. Especially suited for short-circuit rings. |
C021
Our C021 alloy is comprised of chromium copper. Its characteristics are as follows:
| Alloy Group | Alloy | Specification | Nominal Chemical Composition | Yield Strength (psi x 10^3) | Tensile Strength (psi x 10^3) | Elongation % 2" | Brinell Hardness 10 mm/500kg | Modulus of Elasticity (psi x 10^6) | Electrical Conductivity % IACS | Description |
| High Conductivity Copper | C021 | Chrome-Copper | Cu-Cr | 65.5 | 49.7 | 10 | 105 | 17.55 | >=77 | Chromium copper with impressive mechanical properties and electrical conductivity |
C031
Our C031 has the nominal chemical composition of C030
| Alloy Group | Alloy | Specification | Nominal Chemical Composition | Yield Strength (psi x 10^3) | Tensile Strength (psi x 10^3) | Elongation % 2" | Brinell Hardness 10 mm/500kg | Modulus of Elasticity (psi x 10^6) | Electrical Conductivity % IACS | Description |
| High Conductivity Copper | C031 | Copper-Nickel-Silicon | Cu-Ni-Si | 75.3 | 78 | 3 | 190 | 17.35 | 27.6 | Developed for components having large mechancial loads and requiring good thermal and electrical conductivity. No tendency toward stress corrosion; good resistance to atmospheric corrosion. |
Copper Alloys: Featured Information
High conductivity copper chill castings
PIAD chill castings are produced from pure electrolytic copper and provide a minimum of 98% lACS electrical conductivity. This is accomplished by using a metallurgically controlled melting process without the use of fluxes or deoxidation agents. This is a significant difference between PIAD chill castings and sand castings. The copper used for sand castings needs to go through a deoxidation process which results in a reduction in electrical conductivity since impurities remain in the material.
Copper alloys and electricity
The combination of pure electrolytic copper and the PIAD chill casting process provide excellent solutions for design engineers in the electrical industry. PIAD chill castings have replaced many brazed copper assemblies in switches and power breakers, saving labor costs and improving performance.
What customers can expect
Choosing PIAD copper-based castings means choosing exceptionally high heat/electric conductive parts with reduced impurities.
