The usage of various Titanium bars // detailed description
(1). grade 1 can be used in the drawing parts for its good elongation and excellent corrosion-resistance.
(2). grade 2 is used most widely in the commercially pure titanium
(3). grade 3 is almost used in pressure,vessel.
(4). grade 4 can be used in some fittings parts and fastening pieces, but for complex shape need 300 degree celsius to form.
(5). Alloy grade 5(Ti-6Al-4V) widely used in the titanium alloys because of its comprehensive mechanical and chemical properties.
(6). Alloy grade 7 add little palladium in cp titanium and it has the most excellent corrosion-resistance,of course it costs higher.
(7). Alloy grade 9(Ti-3Al-2.5V) is the most widely used in the golf clubs and bicycle girders.
(8). Alloy grade 23, ELI(extra low interstitial),can be used in the medical appliance.
