What is the difference between easy medium and hard silver solder?
Solders come in three types: hard, medium, and easy. Each type has a different melting point. Hard melts at high temperature, medium at a lower temperature, and easy at an even lower temperature.
Is silver solder hard solder?
Silver Solder Alloys Copper (Cu) is soft and a great heat conductor plus it’s resistant to corrosion. Zinc (Zn) and tin (Sn) have really low melting points, which lowers the overall melting point of the solder. All the silver solders sold at Halstead are lead and cadmium-free.
What does hard soldered mean on silver?
Silver soldering, also known as ‘hard’ soldering or silver brazing, is a process in which two or more parts are joined by melting and flowing filler metal into the joint. The melting point of the filler metal is above 420°C and flows into the joint by capillary action.
What is a hard solder?
Definition of hard solder (Entry 1 of 2) : a solder that contains copper, requires a red heat to melt, and is used for brazing. hard-solder. verb.
What is hard solder used for?
Hard solders are used for brazing, and melt at higher temperatures. Alloys of copper with either zinc or silver are the most common. In silversmithing or jewelry making, special hard solders are used that will pass assay. They contain a high proportion of the metal being soldered and lead is not used in these alloys.
Do you need to use flux with silver solder?
Silver Solder is used with a Flux, which chemically cleans the metal and keeps it clean during the Silver Soldering process. Silver Solder is also know as Silver Brazing.
What is hard soldering used for?
“Hard soldering” or “silver soldering” is used to join precious and semi-precious metals such as gold, silver, brass, and copper. The solder is usually described as easy, medium, or hard in reference to its melting temperature, not the strength of the joint.
What is the best flux for silver solder?
Handy Flux is used for easy and medium soldering (solder that melts at a lower temperature) of gold and silver. It can also be diluted with distilled water if it’s too thick. You can buy this from Amazon in 7 oz, 1/2 lb, and 1 lb jars.
