From aerospace engines and electrical power grids to medical devices and advanced microelectronics, discover how brazing plays a critical role in the components driving modern technology. When you look at an aircraft, a power transformer, a refrigeration system, or a medical device, you probably ...

Where AL 822 can fit in HVAC/R Modern HVAC/R systems increasingly combine different materials to reduce weight, manage cost, and improve thermal performance. Aluminum heat exchangers, evaporator components, condenser components, tubing, and transition joints can create repair or manufacturing ...

Cost per pound is only one part of brazing economics When companies compare brazing materials, price per pound is easy to measure. Total process cost is more complicated. The finished joint is affected by alloy chemistry, filler metal volume, flow behavior, form, joint fit, heating cycle, operator ...

The filler-metal form is part of the process design Engineers often spend significant time choosing alloy chemistry and then treat filler-metal form as a secondary detail. In production brazing, that can be a mistake. The same alloy can behave very differently in a process depending on how it is ...

Why electrical brazing is more than a mechanical joint In electrical equipment, a joint may have to carry mechanical load and electrical current at the same time. That means strength alone is not enough. Engineers also care about conductivity, contact resistance, temperature rise, corrosion, ...

Why brazing matters in microelectronics Microelectronic assemblies continue to demand more function from smaller packages. That puts pressure on joining processes to support thermal transfer, electrical performance, hermeticity, dimensional control, and long-term reliability without unnecessarily ...

What is brazing? Brazing is a metal joining process that uses heat and a filler metal to create a metallurgical bond between two base metals. The filler metal melts above 840°F (450°C), but below the melting point of the base metals being joined. Heat can be supplied by torch, furnace, induction, ...

When engineers evaluate a brazing filler metal, alloy chemistry is usually one of the first considerations. But in a production environment, chemistry is only part of the equation. The form, dimensions, tolerances and consistency of the brazing alloy can also influence material usage, process ...

In the ever-growing market of microelectronics, every detail matters. From the design and fabrication of integrated circuits to the assembly of complex electronic devices, precision and reliability are paramount. One critical aspect that often goes unnoticed but plays a pivotal role in achieving ...

Aluminum condensers and evaporators are now found extensively in the HVAC/R field. For installation and repairs, Lucas Milhaupt has the product to get the job done right. Our AL822 is a zinc/ aluminum rod with a flux core, so no separate fluxing step is required. It can be used to both join and ...
