Frequently Asked Questions (FAQ)
Q What is the difference between GR1 and GR2 titanium foil?
GR1 titanium foil features higher purity (≥99.6%) and superior ductility (20% elongation), making it ideal for bending and high-precision components. GR2 titanium foil (≥99.5% purity) has higher tensile strength (345MPa to 895MPa) and excellent fatigue resistance, making it suitable for high-load and harsh environment applications.
Q Which titanium foil grade is best for high-temperature and corrosive environments?
GR2 titanium foil is highly recommended for harsh environments. It is resistant to high temperatures up to 400℃ and strong acid corrosion, making it perfect for aviation, petroleum, and chemical inner wall lining applications.
Q What are the typical applications of GR1 titanium foil?
GR1 titanium foil is commonly used in high-end electronics, such as semiconductor chip packaging carriers, ultra-thin substrates for flexible circuit boards, and micro-battery positive electrode current collectors (down to 0.005mm thickness) to save space.
Q Can GR2 titanium foil be used in food equipment?
Yes, GR2 can be processed into components like mixer shafts for juicers and fixing pins for can sterilizers. It meets FDA hygiene standards, making it safe for food processing equipment.
Q How does GR2 titanium foil perform in conventional electronics?
In general electronics, GR2 titanium foil is used as internal conductive foil and electromagnetic shielding foil for household appliances like air conditioners and refrigerators. It provides reliable protection and conductivity at a controllable cost.
