Special Advantages of Titanium forgings (TC4，TA1，TA2，TC11，TC6)
High Strength-to-Weight Ratio
Comparable strength to steel with only 60% of the weight
Excellent Corrosion Resistance
Resistant to seawater, acids, alkalis, chloride; ideal for harsh environments
High Temperature Performance
Grades like TC11 maintain performance at 400–500°C
Biocompatibility
TA grades are non-toxic and non-magnetic, ideal for medical implants
Superior Mechanical Properties
Forging enhances density, structure uniformity, fatigue and toughness
