Orobraze™ and Pallabraze™ solders are provided in the purity standard “vacuum quality”. V1 indicates that the solder is manufactured in accordance with a strictly controlled requirement for volatile impurities. The solder is therefore suitable for use in vacuum operations, for example in thermionic vacuum tubes. In addition to classic applications in electronics and aerospace, they are used in the glass and chemical industries, where increased resistance to corrosion and chemical stresses of these solders is required.
