In Bronze Fibre made Fillers, bronze is an alloy of copper and tin. Addition of high percentages of bronze powder to PTFE results in a compound having high thermal conductivity and better creep resistance than most other compounds. Bronze Fibre made Fillers is often used for components in hydraulic systems, but is not suited for electrical applications and is attacked by certain chemicals. Bronze has a tendency to oxidize: bronze-filled compounds should therefore be used fresh and containers should always be kept closed. Some discoloration of the finished part during the sintering cycle is normal and has no impact on its quality.
