Titanium sheet plate 8 x 8 inches 3 mm (1/8 inch) thick

For sale is a heavy duty titanium sheet 19.9 centimeters by 21.4 centimeters, or about 8 by 8.5 inches. The thickness is 3 millimeters (1/8 inch). The weight is 571 grams.
The material is pretty smooth and straight overall. It is a soft grade of titanium, easily machined or even cut with a hacksaw.
I have not determined the composition. If necessary, I can submit this tube for X-ray fluorescence analysis. However, I will assume the responsibility for corrosion resistance in weather or saltwater even without analysis performed.
