Frequently Asked Questions

Q: What's the difference between platinum foil and platinum sheet?

A: The terms are often used interchangeably, but typically "foil" refers to thicknesses below 0.25mm, while "sheet" refers to thicker materials. Both offer the same chemical and physical properties.

Q: Can platinum foil be soldered using standard techniques?

A: Standard lead-tin solders don't wet platinum well. Use specialized platinum-compatible brazing alloys or resistance welding for permanent joints.

Q: How do I clean platinum foil without damaging it?

A: Platinum is extremely chemically resistant. You can use aqua regia for heavy contamination, or isopropyl alcohol for light cleaning. Avoid abrasive materials that might scratch the surface.

Q: What's the maximum temperature for platinum foil in air?

A: Platinum can be used continuously in air up to 1200°C. At higher temperatures, it may lose material through volatilization and should be used in controlled atmospheres.

Q: Can I anneal platinum foil to make it more workable?

A: Yes, annealing at 800-1000°C in air or inert atmosphere will soften work-hardened platinum and improve its formability.
