Titanium Strip Wire
Thickness 0.1 – 10.00 mm
Tightest tolerances of 20 µm in width and 5 µm in thickness are possible depending on the dimensions.
Exotic Cross Section titanium strip wire: The titanium strip wire is processed by precision cold rolling, annealing, and surface. Its section is rectangular flat and the thickness is usually 0.1-3mm and the width is 2-100mm. Tolerance on thickness is ±0.01 to ±0.1mm and tolerance on width is ±0.05 to ±0.5mm. The surface roughness Ra is ≤0.8μm, integrating the large strength of metallic materials with flat structure's unique features. For example, the tensile strength of Gr5 titanium alloy flat wire is more than 1000MPa, while the density is 4.5g/cm³. The flat cross section, which was in turn supported by a thin cross section, and in spite of its low weight, the flat cross section had a far superior contact area and structural support compared to round wire materials; its bending stiffness was extremely high. Among them it also meets international standards such as ASTM B265, AMS 4911, etc, quality assurance of performance.

In practical applications, titanium strip wire leverages its cross-sectional advantages to open up diverse pathways:
In the electronics sector, a 0.5mm thick × 10mm wide Gr1 titanium flat wire, after undergoing anodization treatment, is used as a heat sink for 5G base stations. It achieves a 30% improvement in heat dissipation efficiency compared to traditional copper sheets while also providing electromagnetic interference resistance;
In the new energy battery industry, electrode connection strips made from Gr2 titanium flat wire (thickness 0.2mm × width 20mm) exhibit corrosion resistance to organic acids in lithium battery electrolytes for over 5 years, with conductivity comparable to copper while reducing weight by 60%;
In the field of architectural decoration, polished Gr1 titanium flat wire (1mm thick × 30mm wide) is used as a curtain wall decorative strip. With its unique metallic luster and weather resistance, it remains rust-free after 20 years of use in maritime climate environments;
In mechanical manufacturing, Gr5 titanium flat wire (2mm thick × 50mm wide) is precision-pressed into aerospace engine sealing gaskets, maintaining excellent sealing performance even under 400°C high temperatures and alternating stress conditions, with a weight reduction of 45% compared to stainless steel gaskets. Additionally, titanium flat wire serves as shielding components in medical equipment, such as CT devices, leveraging its low magnetic permeability to prevent imaging interference. In the chemical industry, it functions as support mesh bands for heat exchangers, demonstrating significantly superior corrosion resistance to strong acids compared to nickel-based alloys.
The production of titanium flat wire relies on high-precision rolling equipment, where deformation is controlled through multi-pass cold rolling (10-25% per pass). Annealing is performed according to application requirements (recrystallization annealing temperature 650-800°C) to regulate material hardness and ductility. Surface treatments include bright annealing, sandblasting, nickel/gold plating, etc. For instance, Gr5 titanium flat wire, after platinum plating, serves as a bipolar plate flow channel component in hydrogen fuel cells, with hydrogen embrittlement resistance improved by 50%.
