FAQ
Q: Why 0.18mm for aerosol cans?
A: 30% thinner than standard 0.25mm, reducing weight while maintaining 120psi burst strength.
Q: Certification for food contact?
A: Complies with FDA 21 CFR 175.300 & EU 10/2011 (tin migration <0.2ppm).
Q: How does chromium enhance rust resistance?
A: Forms amorphous oxide layer blocking O₂/H₂O penetration at molecular level.
Q: Lead time for 50-ton orders?
A: 20 days with MILL CERTIFICATE and SGS test reports.
Q: Recycling compatibility?
A: Direct EAF feed – coatings vaporize at 1,550°C.
