What sterling silver to use for soldering jewelry?
Typically one solders sterling silver with silver solders. There is not a solder called "sterling solder." You can choose from an array of silver solders ranging from easy (extra soft) through hard. Soft solders have lower silver content and melt at a lower temperature. Hard solders have higher silver content and flow at higher temperatures. If you are doing multiple solder joints on a single piece of solder you will need to use several grades of solder. However, if you are just...
What is the difference between soft soldering and soldering?
The techniques for soft and hard soldering are the same. The difference is in the type of solder used. Soft solder would have a lower melting point and therefore would require less heat. This is usually used for things that can be damaged by excessive heating. ...

Is it possible to solder dress making pins together?
Yes. However, you will not use lead based solder as it is to soft. It would need to use "silver solder" and a small, high energy gas torch - If the pins are end on the weld will be rather fragile ...

What is flux in soldering?
Flux can be in many different forms. it can be in the solder, it can be in a soft form like butter, or it can be in a pen like a tide stain stick. it is used on the solder iron and on the thing you're soldering to make a good surface for the solder to stick to. Basically it makes soldering easier, it can be done with out it. ...

Is silver solder 100 percent silver?
No. 100% silver would be pure silver. Noble silver, Argentium nobalis. which is super soft and shiny. it is very difficult to tarnish. Silver solder is an alloy. An alloy being a mixture of metals. Hard solder is around 67% silver eg. the amount of silver generally goes down as its melting temperature goes down. Soft solder is likely around 45% eg. it could vary massively from company to company and application. A recipe for hard solder is. 1/2 parts tombac brass, to...

What solder do you use on copper tubing for plumbing?
Copper tubing solder "Solder" is an erroneous term as solder mean lead which of course is banned (safe water drinking act) Sweating is another term for "soldering" Copper can be joined by various alloys such as 95 % tin -5% Anatomy or one of the many silver bearing types of low temperature alloys. For the strongest possible joints brazing is the best way to go with a tensile strength over 87,000 PSI compared to soft solder joints of 16,000 PSI For DWV copper joints one...
Asked in Butter and Margarine
Is butter soft or tough?
Unlike many dairy products, you can leave butter out for a few days (preferable in a covered container) and it will not go bad. It becomes soft and easy to spread. When in the fridge, it's fairly tough until it melts in the pan or on warm toast. So, butter can be either depending on temperature. ...

What temperature does stainless become soft?
The temperature at which metals become soft is called the forging temperature. The forging temperature of nonmagnetic stainless steel is 1150 Celsius or 2102 Fahrenheit and the forging temperature of magnetic stainless steel is 1095 Celsius and 2003 Fahrenheit. ...

Why does a chocolate bar become soft beside an oven?
Heat transfer. The oven is warmer than the chocolate bar, which is solid at room temperature. The difference in temperature means that heat will transfer from the warmer oven to the chocolate bar. Chocolate melts at ~36*C, so if enough energy is added to the chocolate, the temperature will rise until it reaches 36*C and begins to melt. ...

What are lead free alloys used for?
A LOT of things...most alloys are lead-free. However...when you see something described as a "lead-free alloy," they're usually talking about a lead-free solder. Soft solder has classically been a mixture of tin and lead due to its low melting temperature and ease of use. Leaded solder is an environmental and health hazard, so people don't want to use it anymore and in many cases CAN'T use it anymore. So...lead-free alloys are used for soldering electrical components and metalwork. ...
