Answers Before You Specify C145
Does C145 copper contain lead?
Tellurium is the selected machining addition in the referenced C14500 composition table; that table does not establish zero trace lead. If your product has a lead limit or other material restriction, specify the actual requirement and agreed test evidence before ordering.
Is C145 copper suitable for electrical connectors?
Review the actual contact design, stock state, current path, contact pressure and working surface. Reference material conductivity supports a material comparison; it does not qualify your complete connector.
Can C145 copper be welded?
Identify the specific welding process, joint design and final material condition. Producer suitability varies by technique; agree joining responsibility and required qualification before accepting a manufacturing route.
C145 copper vs C360 brass: which should I choose?
Compare electrical requirements, contact geometry, stock condition, finish and complete material specification. A free-cutting machinability index does not establish equivalent conductivity or approve a substitution.
C145 copper vs C172 copper: are they interchangeable?
No automatic substitution follows from the word copper. C145 is tellurium copper; C172 is beryllium copper. Confirm exact chemistry, product form, required state and acceptance with your drawing authority.
How much does C145 copper machining cost?
Your C145 copper machining cost depends on stock form and usable material, setups, tool access, edge removal, contact protection, quantities and receiving evidence. For a C145 copper machining quote, compare the same drawing revision and final condition.
What changes between C145 copper half hard vs soft?
Specify the exact temper and product standard. Review forming requirements, cutting support and the finished geometry against that state; do not convert informal hardness names into an unverified material substitution.
What should your C145 copper parts manufacturer review include?
For your C145 tellurium copper machining review, provide the controlled drawing, stock requirement, critical connector fits, accepted edges, finish and inspection scope. C145 copper milling services and C145 copper turning services must follow the same final acceptance.
