Sample analysis：
Above-described embodiment cast molding alloy institute it is stanniferous, there is some difference for zinc metal ingredient, its tensile strength is according to alloy
In each synthetic ingredient ratio it is different and different.
The alloy for choosing above-mentioned cast molding carries out tensile strength test by certain shape and size, its shape is as schemed
Shown in 1.
As shown in Fig. 2, in the case where other tenors are constant, with the increase of Theil indices, the performance of alloy is gradual
Increase, after Theil indices reach 3%, the performance increase of alloy is gentle, and after Theil indices are higher than 3%, the performance of alloy gradually reduces,
It can be seen from the above that when Theil indices are 3%, alloy strength highest.
As shown in Figure 3-4, in the case where other tenors are constant, with the increase of Zn content, the extensibility of alloy
Gradually increase with tensile strength performance, after Zn content reaches 2.5%, the performance of alloy reaches highest level, when Zn content is higher than
After 4%, the extensibility and tensile strength of alloy gradually reduce and less than the performance that Zn content is 2.5%, it can be seen that, when Zn content is
When 2.5%, the extensibility and tensile strength highest of alloy.
