Brake tube
Double wall brazed tube is coated copper on the both sides of the steel strip, and brazed 720

Main Characteristics: 
1. Fine inside cleanness, high strength and nice elongation
2. Good fundation for after-process, anti-leakage. 
3. Anti-high pressure explosion and excellent anti-corrosion properly after surface treatment. 
The tubes can be provided in coils or cut-to length with any length according to the
Requirements from customers
4. The tube is used for auto braking system and power steering system and so on
