0.3mm/0.4mm/0.5mm B/R/S type Platinum Rhodium Thermocouple Bare Wire
An almost endless variety of platinum alloys can be produced based upon individual customer needs. Alloys are generally produced by vacuum arc melting or induction melting. While common alloys used in the jewelry industry are malleable, less common alloys can be very brittle and unworkable.
