GR7 Titanium Wire ASTM B863 density 4.51g per cm3 for Chemical
Equipment
The palladium content in grade 7 (Gr7) titanium wire typically
falls within the range of 0.12% to 0.25%. This particular alloy
surpasses pure titanium in terms of strength and corrosion
resistance, offering an enhanced performance. Additionally, Gr7
titanium wire exhibits a superior ability to withstand high
temperatures without compromising its strength, making it
especially valuable for applications requiring durability at
elevated temperatures.
Introduction:
Grade 7 (Gr7) titanium wire demonstrates robust corrosion
resistance across various media, particularly in neutral and
oxidizing environments. It is also suitable for use in dilute
reducing acids, including different concentrations of nitric acid
at room temperature, and resists corrosion in the majority of
alkaline solutions such as saturated solutions of barium hydroxide,
sodium hydroxide, and magnesium hydroxide. However, it should not
be used in boiling sodium hydroxide solution. Titanium wire remains
uncorroded in seawater and offers resistance to most organic acids,
with the exception of formic acid and oxalic acid. In wet chlorine
and chlorite environments, it maintains excellent corrosion
resistance, and in hypochlorite chloride solutions, its corrosion
resistance is notably high. The corrosion resistance in sodium
chloride solutions is enhanced as the pH value of the solution
rises.
Characterized by its light weight, high strength, commendable
biocompatibility, and impressive corrosion resistance, Gr7 titanium
wire sees widespread application in chemical equipment, the
petroleum industry, and the food industry, with its use extending
into aerospace and biological sectors.
Despite titanium's relatively low electrode potential and highly
reactive properties, it can remain stable without corroding in many
environments. This stability is chiefly due to the rapid formation
of a dense oxide layer on the surface of titanium in the presence
of air or oxygen-containing media, which possesses strong adhesion
and has the capability to self-repair. Compared to other titanium
alloys, titanium-palladium alloys exhibit greater corrosion
resistance in numerous reducing media and demonstrate stronger
resistance to crevice corrosion. The palladium content contributes
a cathodic effect that alters the anodizing properties of titanium,
making it an effective alloying element for enhancing the
material's performance.
