Cad iad Tréithe Cóimhiotal Stáin Luaidhe

1. Tá feidhmíocht chobhsaí ag cóimhiotal luaidhe-stáin, pointe leá íseal, sreabhach maith agus crapadh beag.

2. Tá gráin mhín, cruas maith, cruas oiriúnach agus bog, dromchla réidh, gan poill gainimh, gan aon lochtanna, gan scoilteanna, agus dea-éifeachtaí snasta agus leictreaphlátála ag an gcóimhiotal luaidhe-stáin.

3. Tá dea-fheidhmíocht agus toughness ag réitigh lártheifeacha cóimhiotail luaidhe-stáin, agus féadann sé páirteanna cruinneas a chaitheamh le cruthanna casta agus ballaí tanaí, agus tá dromchla na teilgin réidh.

4. Lead-tin alloy products can be surface treated: electroplating, spraying, painting.

5. Tá struchtúr dlúth criostail ag an gcóimhiotal luaidhe-stáin, rud a chinntíonn go bhfuil an caoinfhulaingt méid réitigh beag, go bhfuil an dromchla fíorálainn, agus is beag na lochtanna iar-phróiseála.

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.
