Brazing Services

We are a brazing company and global leader in the field of advanced material joining technologies for high vacuum applications. Our brazing services leverage precision vacuum and furnace brazing technologies to provide our customers cost savings, batch processing and the highest quality in the industry.

We braze and clean fire virtually all low vapor pressure metals and ceramics such as OHFC Copper 101,Stainless Steel (SST), Kovar, Monel, Tungsten, Cupro-Nickel, Titanium, Aluminum, Alumina, Silicon Carbide and many more.

Our furnace brazing services or vacuum brazing services are available via consignment or turnkey production services. We encourage the turnkey route because it lowers overall risk for you.  Consignment is a good fit when customers are experts in braze-joint design and can provide high-quality pre-machined material for processing. If desired, we can also provide stress-relieving, tempering and secondary finishing operations via our in-house CNC machining department upon request.

Brazing Furnaces

Furnace technology provides the highest quality joints and is the only technique well adapted for complex geometries, ceramic-to-metal bonding, large/massive parts, or highly reactive materials because assemblies are heated uniformly and multiple joints are processed simultaneously. We primarily supply services and products into high-vacuum, Ultra-High Vacuum (UHV), or “clean” applications and DO NOT use any flux in our advanced material joining processes.  Our services include atmosphere brazing, hydrogen brazing, vacuum furnace brazing services, diffusion bonding, bakeout for high vacuum applications and heat treating.

LAM & AMAT Approved Supplier

We process assemblies in high vacuum furnaces with the multi-zone controls required to accurately control tight tolerances and strong braze joints. Today Altair has innovated ways to braze copper, stainless steel, and other refractory metals to aluminum while avoiding brittle intermetallic phases, leaving a strong and hermetic bond. We have also developed an accurate brazing technique for achieving a 360-degree thermal bond on a heating element surrounded by aluminum.

Dual Bell Sauder Bakeout Station

A processing step for UHV (ultra-high vacuum) applications. We continue to add core and complementary capabilities like bakeout and have always been leaders and innovators in this regard.

• 6 Independent Cryogenic Ports
• Two Independent Bells
• x10-9 scale vacuum pressure
• Temp. > 600°C and > 1000°C
• Automated Controls
• Ultra-High Vacuum (UHV)
• Efficient Device Conditioning
• Flexible Configuration
• RGA Measurements

Material Joining without the use of filler

High compression and temperatures cause atoms to diffuse into the adjacent material for metal, copper, and titanium. This particular bonding process is commonly used on linear accelerators and mini-coolers, where braze joints and braze fillets can shift the resonant frequency of a cavity or add a very thin thermal shunt layer which is avoided in diffusion bonding.

Precision Welding

Includes Tig and Spot Welding

Precision welding rounds out our full spectrum of material joining capabilities to support our contract manufacturing and turnkey services. Welding is both an art and a science. We take pride in our beautiful and full penetration welds because they are a prime example of our commitment to quality and the highest standards of fabrication.

We weld Titanium, Nickel, Stainless Steel, Platinum, Kovar, and Moly for spot, stitch and continuous hermetic (vacuum-tight) welds.
