Pure Copper
Very high electrical and thermal conductivity with good corrosion resistance and formability.
Copper Alloy Selection Guide
Choose a copper alloy around conductivity, strength, and manufacturability.
Compare copper, brass, bronze, beryllium copper, and specialty alloys by conductivity, corrosion resistance, strength, machining, forming, joining, wear, and availability.
Selection Overview
Start with the complete service environment.
Copper alloys span materials optimized for electrical conductivity, thermal transfer, corrosion resistance, bearing performance, spring properties, machinability, appearance, and marine service. Alloy selection should consider conductivity, mechanical load, wear, corrosion, forming, machining, brazing, soldering, plating, and product form.
Comparison Criteria
Material families and performance factors to review.
Use consistent technical and sourcing criteria so candidate materials, grades, and suppliers can be compared on the same basis.
Brass
Copper-zinc alloys offering machinability, formability, appearance, and useful corrosion resistance.
Bronze
Copper alloys commonly selected for wear, bearings, corrosion resistance, and cast components.
Beryllium Copper
High-strength copper alloy with spring performance, conductivity, and non-sparking applications.
Phosphor Bronze
Spring, fatigue, wear, and corrosion performance for contacts, bushings, and formed parts.
Aluminum Bronze
High strength and strong corrosion resistance in marine and demanding industrial environments.
Free-Machining Alloys
Copper alloys developed for efficient machining, dimensional control, and high-volume components.
Temper and Product Form
Annealed, hard-drawn, spring temper, sheet, strip, bar, tube, wire, plate, and cast forms.
Specification Details
Provide enough information for an accurate material recommendation.
Conductivity Requirements
Define electrical current, thermal transfer, contact resistance, and allowable conductivity loss.
Mechanical Load
Specify strength, hardness, spring behavior, fatigue, bearing load, impact, and wear.
Environmental Exposure
Identify seawater, chemicals, moisture, temperature, galvanic contact, and atmosphere.
Manufacturing Route
Clarify machining, stamping, forming, drawing, casting, forging, extrusion, or wire production.
Joining and Finishing
Include soldering, brazing, welding, plating, polishing, coating, and contact surfaces.
Material Form and Certification
State sheet, strip, bar, rod, tube, wire, casting, specification, temper, and traceability.
Selection Workflow
A practical path from operating conditions to material approval.
Define the primary function
Prioritize conductivity, strength, wear, corrosion, spring behavior, or appearance.
Choose the alloy family
Match pure copper, brass, bronze, beryllium copper, or specialty alloys to the need.
Select temper and product form
Balance strength, ductility, spring properties, machinability, and forming.
Review joining and surface requirements
Confirm soldering, brazing, welding, plating, polishing, and corrosion compatibility.
Verify supply and documentation
Check specification, certification, lead time, mill form, minimum order, and traceability.
