Koje su karakteristike izvedbe olovo-kositrnih legura?
Dec 10, 2021
1. Legura olova i kositra ima stabilne performanse, nisku točku taljenja, dobru fluidnost i malo skupljanje.
2. The lead-tin alloy has fine grains, good toughness, suitable hardness and softness, smooth surface, no sand holes, no defects, no cracks, and good polishing and electroplating effects.
3. Centrifugalno lijevanje od legure olova i kositra ima dobre performanse i žilavost i može lijevati precizne dijelove složenih oblika i tankih stijenki, a površina odljevaka je glatka.
4. Proizvodi od legure olova i kositra mogu se površinski obrađivati: galvanizacija, prskanje, bojanje.
5. Legura olova i kositra ima gustu kristalnu strukturu, što osigurava da je tolerancija veličine odljevka mala, površina izvrsna, a nedostataka nakon obrade malo.
In the acidic electrolyte of simple complex ions, the lead-tin alloy can be co-deposited at a very low current density, and the lead-tin alloy coating has a lower porosity than the lead and tin coatings of the same thickness. The lead-tin alloy containing 60% tin and 40% lead has the lowest eutectic point of 183 °C, and its soldering performance is far superior to that of pure tin plating. Therefore, it has been widely used in aerospace, electronic and electrical industries. Stable performance, low melting point, good fluidity and small shrinkage. Fine grain, good toughness, suitable hardness and softness, smooth surface, no sand holes, no defects, no cracks, good polishing and electroplating effect.
