The word "braze" is spelled with a letter "z" even though the sound is pronounced as "s". This is because the word has its origins in the Old French word "braser" which was spelled with a "z". The IPA phonetic transcription for "braze" is /breɪz/, with the "z" sound represented by the symbol /z/. The pronunciation is slightly different from the word "brace", which is spelled similarly but has a different meaning and pronunciation (/breɪs/).
Braze refers to a metallurgical process used to join together two or more pieces of metal using a filler material that has a lower melting point than the metals being joined. The aim of braze is to achieve a strong and permanent bond between the metals, increasing their overall strength and structural integrity.
During the braze process, heat is applied to the metal parts being joined, causing the filler material to melt and flow between the mating surfaces. The molten filler material acts as a sort of adhesive, bonding the metals together when it solidifies. Commonly used materials for brazing include copper, silver, and aluminum alloys, which exhibit good wettability and compatibility with a wide range of metals.
The braze technique finds wide applications in various industries, such as automotive, aerospace, and plumbing, for joining components that cannot be welded using conventional methods or where the use of welding may lead to distortion or damage to the workpiece. Brazing is particularly suitable for joining dissimilar metals, as the filler material can accommodate the differences in thermal expansion and contraction rates.
In summary, braze is a metallurgical process wherein a lower-melting-point filler material is used to join two or more metal pieces by melting and bonding them together. This technique provides a reliable and strong connection, making it an essential method for joining metals with different compositions and properties.

The word "braze" originated from the Middle English verb "brasen", which was derived from the Old English word "bræsen". This Old English term ultimately came from the Proto-Germanic root "*brasnāną", which means "to solder". The Proto-Germanic root is also related to the Old Norse word "brasa", meaning "to harden by fire", and the Old High German word "brasan", meaning "to set on fire". The etymology of "braze" traces back to the Germanic languages and reflects the ancient practice of joining metal pieces by heating and melting a filler metal.
