Benefits of technology

This patented technical effect of this patents relates to improving the quality and efficiency of producing specialized metal alloys for various applications such as electronics or energy storage devices. These alloys have improved mechanical qualities like higher yield point impacts and reduced costs while also maintaining their desired physical attributes. They offer better heat conductivity, ductility, creep behavior, and corrosive resistances than existing alternatives. By optimally combining different components together, these compositions provide superior overall performances without adding extra steps.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the mechanical characteristics (strength) or durable life of electronic parts made from metal nitride solder that resist erosion under various environments such as air conditioned conditions during storage and transportation without losing functionality overtime due to damage caused by environmental factors like moisture and oxygen. Existing solutions involve modifying the chemical formula based on specific metals found within these compositions but they often result in decreased conductance or reduced tensile property compared to desired levels.

[0030] The alloy of the present invention is smelted using the following raw materials: electrolytic copper, ingot sheet, iron sheet, pure tin, zinc ingot, copper-phosphorus alloy, rare earth element RE, nickel-boron alloy.

Embodiment 1

[0032] The composition of the alloy is shown in Example 1 of Table 1.

[0033] In step a, the specific order of the feeding is: first add copper (Cu), nickel (Ni), iron (Fe), and then add tin (Sn) and zinc ingot (Zn) at a low temperature after melting, and wait until they are all melted Copper-phosphorus (Cu-P), rare earth (RE) alloy and nickel-boron alloy (NiB) were added at low temperature (added after smelting zinc, the main purpose is to reduce oxidation burning loss and achieve uniform and stable composition), and the composition test passed After the slag is cleaned, it is covered with baked charcoal; a power frequency induction furnace is used for melting and casting in a non-vacuum environment, and the casting temperature is controlled at 1195° C., and the horizontal continuous casting method is used for casting.

[0034] Among them, the requirements of the horizontal continuous casting casting process are as follows: the pulling length is 10.5mm, the time between draw...

Embodiment 2

[0044] The composition of the alloy is shown in Example 2 of Table 1.

[0045] In step a, the specific order of the feeding is: first add copper (Cu), nickel (Ni), iron (Fe), and then add tin (Sn) and zinc ingot (Zn) at a low temperature after melting, and wait until they are all melted Copper-phosphorus (Cu-P), rare earth (RE) alloy and nickel-boron alloy (NiB) were added at low temperature (added after smelting zinc, the main purpose is to reduce oxidation burning loss and achieve uniform and stable composition), and the composition test passed After the slag is cleaned, it is covered with baked charcoal; a power frequency induction furnace is used for melting and casting in a non-vacuum environment, and the casting temperature is controlled at 1210° C., and the horizontal continuous casting method is used for casting.

[0046] Among them, the requirements of the horizontal continuous casting casting process are as follows: the pulling length is 11.0mm, the time between draw...
