Let’s break down what makes our platinum tungsten wire stand out. It’s an alloy of mostly platinum—90-95%—with 5-10% tungsten to boost its strength and thermal stability. This gives it a tensile strength of 50-70 ksi and electrical conductivity of 15-20% IACS, perfect for thermocouples that need to transmit precise signals. With a melting point around 1770°C, it thrives in high-heat environments where other materials would fail. It’s also corrosion-resistant, standing up to oxidative atmospheres, acids, and industrial gases without degrading. Whether it’s measuring temperatures in a turbine or a steel mill, our wire ensures your thermocouples stay accurate and reliable.
