I'm not sure but Aluminum bronze would probably give you the best
of luck and good life.I use it a lot for thread roll pins and am amazed at the life I get out of it.100,000 3/8 16 parts and no adjustment yet!!In 1018 yet!!
Leaded steel C12L14 will give you an excelent finish but will not give much
life.Use lots of oil and do not abuse and will last a reasonable time though.
Your life with these softer materials will depend a lot on your finishes on the threads.The beter the finish the longer it will last.
Have fun and keep it simple. |
