Frequently Asked Questions
-
What is the typical magnetic flux density of your tinplate strip?
Our tested values generally show B800 ≥ 1.5 Tesla, but specific results depend on the hardness grade and coating weight. We provide test reports with each shipment. -
Can you supply strips narrower than 8mm?
Yes, we can slit down to 5mm for special orders. Please contact our sales team to discuss minimum order quantities. -
What is the difference between T2 and T5 hardness?
T2 is softest (HR30T 46-52), ideal for deep drawing; T5 is hardest (HR30T 65-70), suitable for applications requiring high rigidity and magnetic saturation. -
Do you offer matte surface finish?
Yes, both bright and matte finishes are available. The matte finish is often preferred for better adhesion of coatings or laminates. -
How do you ensure the magnetic properties are consistent across the coil?
We perform magnetic flux density testing at multiple points along the strip using a calibrated B-H loop tester, and we provide a certificate of analysis. -
What is the minimum order quantity (MOQ) for custom widths?
Typically 3 tons per size for standard widths, but for narrow strips (below 30mm) the MOQ may be 1 ton. Please inquire. -
Can you supply tinplate strip with lead-free coating?
Yes, our tin coating is lead-free and complies with RoHS regulations. We can also provide REACH-compliant material upon request.
