Bundy Tube – Double-Wall Copper-Plated Low-Carbon Steel Tube for Automotive Use Material Overview Bundy tube is a double-wall low-carbon steel tube manufactured by rolling a steel strip into a 720° overlap and copper-brazing the seam. This produces a concentric double-wall tube with a continuous brazed bond between the two walls. For automotive brake and fuel lines, this design offers: The mechanical strength and rigidity of steel The corrosion protection and brazeability of

SAE J527 Bundy Tube Double-Layer Copper-Plated Low-Carbon Steel Tube for Brake Line Material SAE J527 double-layer copper-plated low-carbon steel tube, commonly known as Bundy tube, is a precision-formed, copper-brazed steel tubing product used in brake, fuel, hydraulic, and refrigeration systems. SAE J527 covers brazed double-wall low-carbon steel tubing for applications that require reliable bending, flaring, beading, forming, and brazing, while ASTM A254 covers the closely

SAE J526 Welded Low-Carbon Steel Tubing (Coiled) for Brake & Hydraulic Lines Material SAE J526 tubing is an electric-resistance welded (ERW), single-wall low-carbon steel tube supplied in coils (or straight lengths) for automotive fluid conductor applications where controlled bending, flaring, beading, forming, and brazing are required.Important design note: SAE J526 material is not intended for single-flare applications due to a potential leak path associated with the

E355+N Carbon Steel Seamless Hollow Bars Cold Drawn Precision Tube for Mechanical Applications Material E355+N is a non-alloy carbon steel seamless precision tube grade, steel number 1.0580, commonly used in the EN precision-tube and mechanical-tube system. In practical sourcing, it is generally treated under EN 10305-1 for seamless cold drawn precision tubes and can also align with EN 10297-1 for seamless tubes used in mechanical and general engineering. The “+N” delivery

Galvanized Bundy Tube Hot-Dip Galvanized Precision Bundy Tube For Automobile Brake Material Galvanized Bundy tube is a double-wall, copper-brazed low-carbon precision steel tube designed for automotive fluid line service. In brake-line applications, the core value of this product is the combination of a compact double-wall structure, stable forming behavior, and protected outer surface for corrosion resistance. SAE J527 and ASTM A254 both describe this double-wall copper

DIN 1630 St 52.4 Cold-Drawn Seamless Precision Tube for Hydraulic System Material DIN 1630 St 52.4 (ST52.4) is a high-performance non-alloy carbon steel used to produce seamless, cold-drawn precision tubes for demanding service such as hydraulic and pneumatic systems, pipework, vessels, and general mechanical engineering.In many supply chains, St52 / St52.4 is cross-referenced to EN grades such as E355 (1.0580) for hydraulic precision tubes. Specifications Product type: Cold

25CrMo4 Seamless Cold Drawn Precision Tube (EN 1.7218) for Racing & Motorsport Material This product is a seamless, cold-drawn precision steel tube made from 25CrMo4 (steel number 1.7218)—a chromium-molybdenum low-alloy, low-to-medium carbon steel designed for quenching and tempering to achieve an excellent strength-to-weight ratio, toughness, and fatigue resistance.For racing and high-load mechanical parts, 25CrMo4 is widely used as an equivalent of SAE/AISI 4130 in many

Bright Annealed Stainless Steel Tubing (Cold-Drawn Seamless) for Automobiles Material Overview Bright Annealed (BA) stainless steel tubing is a cold-drawn seamless tube that is solution annealed in a controlled, oxygen-free (reducing or inert) atmosphere to preserve a clean, bright metallic surface on both the OD and ID, while restoring ductility after cold working. For automotive systems, BA seamless tubing is typically selected when you need: High corrosion resistance and
