hard solder
Definition
Noun: A type of solder, specifically one that contains copper and melts at a relatively high temperature. It is primarily used for brazing, a process of joining metals.
Usage
"Hard solder" is a technical term used in metalworking, engineering, and jewelry making. It refers to a high-strength filler metal used to join pieces of metal. Unlike soft solder, it requires a higher temperature to melt and creates a much stronger, more durable joint.
Examples
- Noun:
- The jeweler used hard solder to join the silver links, ensuring the bracelet would not break.
- For the copper pipe fitting, a hard solder containing silver was chosen for its strength and resistance to heat.
Advanced Usage
- Technical Context: In metallurgy, "hard solder" often implies a filler metal with a melting point above 450°C (842°F), distinguishing it from "soft solder." Its composition can include not just copper, but also silver, zinc, or other alloys to suit different base metals.
- Process Specification: The term is frequently used when specifying the brazing technique, as in: "The assembly must be joined using a hard solder brazing process."
Variants and Related Words
- Brazing Alloy: A more general term for filler metals used in brazing, which includes hard solders.
- Silver Solder: A common type of hard solder that contains a high percentage of silver.
- Soft Solder: The contrasting term for solder with a lower melting point, typically made of tin and lead.
Synonyms
- Brazing solder
- High-temperature solder
- Strong solder
Related Phrases
- To flow hard solder: Refers to the process of heating the solder until it melts and flows into the joint.
- You need a precise torch to properly flow the hard solder along the seam.
Noun
-
solder that contains copper; melts at a relatively high temperature; used for brazing
