所以普拉塔就像一个小小的银，但我们现在知道普拉塔比银要好很多,更为珍贵，熔点更高，化学惰性更高，是一种非常不可思议的金属。
So platina is like a diminutive of silver, but we now know that platinum is far superior to silver It is far more noble. It has a higher melting point, a higher chemical inertness, a fantastic metal.
银焊料、设置之间的核心部分，加热至熔点以上的债券为核心的部分。
A silver solder, placed between the segment and the core, is heated above the melting point to bond the segment to the core.
含银量高、熔点稳定，具有优异的渗透性和流动性，适于焊接薄膜、温控、电器装置等接触面小的工件；
Alloys with a high silver content, small melting range, excellent capillarity and fluidity. Used for brazing thin joints such as diaphragms, thermostats, electrical equipment, etc.
银具有最高的导电率和导热率，但熔点低，硬度低，易产生硫化物膜。
Silver has the highest conductivity and thermal conductivity, but the low melting point, low hardness, easy to produce sulfide film.
