Metal Parts Treatment - Brazing Services

Our Mission and Values define our commitment (See our Mission and Values).
You can be certain your business will receive our full attention. Brazing is our business, not just a part of it.

Brazed Metal Parts

Better Processes

The PuroBrite™ system. We are the only company with the PuroBrite™ system.

Our processes are simply better. We guarantee it.

Our use of pure atmospheres and continuous furnaces is unique. This combination produces the cleanest brightest parts with the strongest joints. These conditions are ideal for stainless steels. Your parts will meet the exacting standards of the design expected by your customer.

Highest Quality

We optimize first pass yields. This lowers your cost and makes you more competitive. We review and consider all factors to maximize yields. See how we are doing along with our whitepaper 7 Ways to Lower Scrap. Your costs will be consistently low.

Why Brazing?

Brazing can be traced back to ancient Egypt in the days of the Pharaohs. It is a proven economical way to permanently join metals. Properly designed and brazed joints are actually stronger than the base metals of the components. Unusual shapes and multi-joint designs can be brazed in bulk without special fixtures. It is also possible to join dissimilar metals and thin gages. Brazing is often a superior option to welding.

Potential advantages of brazing include:

  • Lighter weight components
  • Stronger assemblies
  • Complex assemblies from common parts
  • Efficient designs (e.g. stainless and mild steel combinations)
  • Elimination of special tooling or fixtures
  • Elimination of other processes like machining, staking or threading
  • Leak-tight and attachment properties
  • Multi-joint processing in a single pass
  • Permanent joints
  • Uniform stress relief throughout


What is Brazing:

Temperature Ranges for Brazing Different MetalsBrazing is a process in which two metals are joined together using a filler metal whose melting point is above 840° F but below the melting point of the base metals being joined. The filler metal is distributed between the closely fitted metal surfaces by capillary action.

Brazing Range:

The total temperature range over which the filler metal should be able to be used. (Refer to temperature range chart for various filler metals)

Capillary Action:

A phenomenon of surface tension which causes a liquid to be drawn into the space by two closely mated parallel surfaces. In order to achieve capillary action, the surfaces must be close (no more than .010″), parallel, and clean of any oxides or oils.


Excess alloy remaining on the edge or edges of a brazed joint forming a build up area.

Protective Atmosphere:

A gas surrounding the work pieces, used to prevent, or facilitate the removal of, oxides and other detrimental surface substances.
