Frequently Asked Questions:
Q: What tolerances can be achieved for custom-sized plates?
A: Standard dimensional tolerances adhere to ASTM B388 specifications. Precision grinding can achieve ±0.025mm tolerances for critical applications.
Q: Can you provide material certification documentation?
A: Yes, we supply full material traceability with mill test reports including chemical composition and mechanical property verification.
Q: What is the typical lead time for custom orders?
A: Standard sizes ship within 2-3 weeks. Custom dimensions require 4-6 weeks depending on complexity and quantity.
Q: How does 4J36 compare to other low-expansion alloys?
A: 4J36 offers superior thermal stability at room temperatures compared to alternatives like Kovar or Super Invar, with better machinability.
Q: What packaging is used for international shipments?
A: We use weather-resistant wooden crates with anti-corrosion VCI paper and edge protection to ensure damage-free transit.
