Products Description
Our Advantages
1.Ultra-High Strength
- The Beryllium Copper Tube is made from UNS C17200 material, one of the strongest copper alloys, and undergo solution treatment and age hardening. Their tensile strength and yield strength can approach that of alloy steel.
- The tubes undergo rigorous mechanical property testing to ensure their strength meets ASTM B643 standards, making them ideal for high-load and high-pressure applications such as springs, diaphragms, and aerospace components.
2. Excellent Electrical and Thermal Conductivity
- Our tubes are tested using a spectrometer to strictly control the beryllium content, ensuring it meets ASTM B643 standards. This maintains the optimal range, avoiding reduced conductivity due to excessive beryllium content and limited strength due to insufficient beryllium content.
- The Beryllium Copper Tube maintains the continuity of the copper matrix through precise heat treatment and aging processes, achieving high electrical conductivity.
3. Excellent Fatigue and Wear Resistance
- Our tubes are seamless tubes manufactured using a cold drawing process, and eddy current testing is performed to ensure uniform wall thickness and no internal defects, maintaining long-term reliability under repeated stress.
- The tubes undergo pickling and cold drawing processes, resulting in a smooth surface that is polished to remove oxides, scale, and surface defects, reducing friction and wear and enhancing the wear resistance of the tubes.
4. High Dimensional Accuracy
- Our C17200 Beryllium Copper Tubes are manufactured through precision extrusion and drawing, with strict control of the outer diameter tolerance within ±0.05mm, ensuring compliance with ASTM B643 dimensional standards.
- Every tube produced by TORICH undergoes rigorous dimensional inspection to ensure precise matching with connectors, fittings, and machined parts.
