The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids, such as arsenic or silicon.
The typical test uses a 10 mm (0.39 in) diameter steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force.For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball.

It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.
China-based DJI could be banned from launching new drones in the United States market under an annual military bill set to be voted on later this week by the U.S. House. The 1,800-page bill says a ...
At 500 °C it is still 0.8% Si, at 400 °C 0.3% Si and at 250 °C only 0.05% Si. At room temperature, silicon is practically insoluble. Aluminum cannot be dissolved in silicon at all, not even at high temperatures. Only in the molten state are both completely soluble. Increases in strength due to solid solution strengthening are negligible. [7]
