Thickness and Uses of Titanium Foil Coil

Titanium foil and coil are cost-effective lightweight and corrosion-resistant materials in the industrial field, produced in accordance with the American standard ASTM B265. With the characteristics of thickness gradient and performance differentiation, they cover all scenarios from precision electronics to chemical energy. The main difference between the two is the range of thickness: titanium foil is for the ultra-thin titanium sheet with thickness less than 0.1mm while titanium coil is for medium thickness of titanium strip with thickness from 0.1mm to 4.75mm. Different thicknesses correspond to exclusive grades and application scenarios. The following provides a detailed analysis from three aspects: specification parameters, performance matching, and market trends.

1. Ultra thin titanium foil (0.005mm – 0.02mm, GR1)

Performance: Purity ≥ 99.6%, excellent plasticity, can bend tens of thousands of times without cracking, and has the best corrosion resistance.

Application: Solid state battery current collector, 3C electromagnetic shielding film, microsensor substrate, medical ultra-thin gasket.

Market: High end electronic customization is the main focus, with a price of about 80-120 USD/kg and a delivery time of 7-15 days.

2.Titanium foil for precision (0.02mm-0.1mm,GR1/GR2)

Performance: GR1 is easy to process, GR2 has slightly higher strength, surface Ra ≤ 0.2 μ m, suitable for precision stamping.

Application: Flexible circuit substrate, chemical sealing gasket, food grade filter screen, decorative coating substrate.

Market: Main specifications for chemical and electronic industries, with ample stock of GR2 at a price of $35-50 per kilogram.

3. Standard titanium coil (0.1mm-1.0mm, GR2)

Features: Industrial pure titanium with excellent tensile strength in the range of 345-480MPa, resistant to acid, alkali and chloride ion corrosion.

Application: lining for chemical equipment, fins of heat exchanger, components for seawater desalination, bipolar plates for new energy batteries.

The Market: Most affordable and highest utilization (utility) value, the price is between $28 and $38 per kilog. and can be customized on small order.

4. Thick titanium coil (1.0mm – 4.75mm, GR2/GR5)

Performance: There are corrosion resistant applications for GR2 and high temperature resistant applications for GR5 (Ti6Al4V) with a strength of ≥ 930MPa.

Applications: Liter insulate aviation high pressure vessel lined with, automobile exhaust system, marine engineering structure Parts.

The Market: GR5 prices can go from $60 to $90 per kilo and a lead time for production is required. High end specifications rely on precision cold rolling.

Price rule: The thinner the thickness, the higher the price, GR1>GR2>GR5 (same thickness); The price for customized widths exceeding 1000mm will increase by 15% -20%.

Supply characteristics: 0.02mm-1.0mm GR2 titanium coils are available in stock with a delivery time of 3-7 days; 0.005mm ultra-thin foil and GR5 thick roll are mainly customized, with a delivery time of 15-30 days.

Material selection principle: Select GR1 ultra-thin foil for precision electronics, GR2 standard roll for general industry, and GR5 thick roll for high-strength working conditions; Due to limited budget, priority should be given to GR2 specifications ranging from 0.2mm to 0.5mm, balancing performance and cost.

The core value of Titanium Foil and Coil lies in its thickness grading adaptability to different scenarios and grade matching performance. Ultra thin foil is mainly used for precision and flexible applications, balancing corrosion resistance and processability. Standard coils meet the general needs of industry, while thick coils are suitable for high-strength and heavy-duty working conditions. Titanium foil and coils produced in accordance with ASTM B265 standards have gradually replaced traditional materials such as stainless steel and aluminum with their core advantages of lightweight, corrosion resistance, and non-magnetic properties, becoming the core material for high-end manufacturing and industrial upgrading.
