When it comes to shots at Indium Corporation, it is not about bullets, vaccines, or vodka; it’s about small spherical or tear-drop shaped forms of metals and alloys. While ingots and cakes are more popular forms when we think about metals and alloys, shots have their exclusive benefits.
Shots provide a larger area-to-volume ratio for the metals and alloys that favor the interaction with external factors. Afterall, dissolving a certain volume of metal in a solution is much easier and faster with small pieces than with a single bulk quantity. For instance, considering a 500g indium ingot with dimensions of 7” × 1.25” × 0.5” versus several indium shots of 0.125” diameter with the same total weight, the ratio of surface area exposed to the solution is nearly 8 times higher for shots. Therefore, if surface area is the limiting factor in dissolving indium in a chemical solution, shots would ideally dissolve 8 times faster.
使用較小熔膠罐的工程師會發現，當鑄錠過大而無法裝入時，使用噴射會很有幫助。鑄件提供更佳的供料量解析度。我們可以輕鬆地秤出更精確的小量鑄件，這在使用較大的金屬和合金時很難實現。這也有助於減少鑄錠銼削後的廢料。除此之外，球形或水滴形金屬和合金的儲存、處理和供料也更為方便。
噴丸通常是將熔融金屬通過小圓孔製成。然後，熔融金屬進入冷卻溶液，凝固成射丸。噴丸經過乾燥、退火或進一步加工，以達到穩定與硬化的目的。圓形開口的大小和沿著溶液通過的長度，決定了噴丸的大小和形狀。
Shots in general have a lower shelf-life compared to larger-sized forms because of the larger exposed area, which increases the interaction with external elements like oxygen, humidity, etc.
Indium Corporation produces spherical and tear-drop shaped shots for different metals and alloys. This list includes, but is not limited to, indium, gallium, germanium, tin, Indalloy®117, Indalloy®136, and Indalloy®158. The purity that we provide ranges from 3N to 6N5. Readily available shots are approximately 0.125” in diameter and can be adjusted based on customer requirements and quantity. We can also manage the uniformity in size as required.
