Working with C93200 As Cast
Is C93200 easy to machine?
Excellent free-cutting behaviour (~70 % of C36000); use sharp positive-rake tools, high speed, light feeds and flood coolant — lead gives short chips and fine bores.
Can C93200 be welded?
Not weldable — lead causes hot cracking and fumes; repair by mechanical means or replace, soft soldering is acceptable.
Can C93200 be formed, bent or molded?
Casting alloy only: good fluidity for sand, continuous, permanent-mold and centrifugal casting; no cold forming, hot working not practised.
What surface finishes work on C93200?
Machine or burnish bores to size; tin, nickel or silver plating and light polishing work well, no anodizing; handle lead-bearing swarf per local regulations.
