Product Overview
Our soft magnetic pure iron billets are specifically engineered for precision CNC machining applications requiring exceptional magnetic properties and consistent mechanical performance. Manufactured through vacuum melting technology, we guarantee material purity exceeding 99.8% with controlled low levels of carbon (<0.015%), sulfur (<0.010%), and phosphorus (<0.015%).
These billets deliver:
Superior magnetic permeability (μ up to 5,000)
Low coercive force (<80 A/m)
Minimal core loss
Excellent temperature stability
Consistent batch-to-batch performance
Available in standard sizes from 50mm to 300mm diameter, with custom dimensions and special tolerances available for OEM applications.

FAQ
Q: Do you offer material testing samples?
A: We provide test coupons from the same heat for evaluation. Sample size typically matches your planned machining stock.
Q: What's your lead time for custom compositions?
A: Standard compositions ship in 10-15 days. Custom alloys require 3-4 weeks for production and testing.
Q: How do you ensure magnetic consistency?
A: We perform 100% magnetic testing on master samples from each production batch and maintain strict control over chemical composition and heat treatment.
Q: Can you match specific international standards?
A: We regularly produce materials meeting ASTM A848, IEC 60404-8, and DIN 17405 standards, and can customize to match your required specifications.
Q: What packaging do you use for CNC billets?
A: We use protective coating, individual wrapping, and custom wooden crates to prevent surface damage during transit and storage.
