HONEYCOMB CORE PRODUCTION WITH SUPER ALLOYS

SILMEC SRL, specialising in the production of Honeycomb Cores in Italy. Capable of guaranteeing very short lead times.

With more than 20 years of experience in the production of steel and special alloy components for the power generation, aerospace and medical sectors, and thanks to a strong technological know-how, we can claim to be probably the only producers of Honeycomb Cores in Italy, able to guarantee very short lead times.

Honeycomb Cores

Honeycomb Cores are made from super alloys, which are used in many applications due to their excellent combination of lightness and strength. These components are essential in strategic sectors requiring high-performance materials, such as the aerospace and power generation industries.

Embedded Braze Tapes

In the production of Honeycomb, for special requirements and industrial contexts, we can perform the application of a brazing paste mat on the manufactured components. The tape is cut and positioned to size.

The benefits of this service
  • Reduced costs and increased efficiency:

    the pre-embedded brazing tape makes Honeycomb products ready to use. It avoids the application of brazing paste, thus reducing processing time.

  • More precision:

    the use of pre-embedded tapes allows more precise and controlled distribution, reducing the risk of waste compared to other less precise manual methods of applying brazing paste.

  • Less complex heat treatment and less harmful emissions:

    brazing tapes reduce the need for complex heat treatment, the use of harmful chemicals for surface treatment and exposure for operators. This also means less environmental impact and fewer health risks.

  • Standard Specifications:

    The requirements for the pre-embedded brazing tapes we use refer to the AMS-4777 / AMS-4778 / AMS-4779 / AMS-4782 / AMDRY-103 / AMDRY specifications that define the chemical, physical and mechanical characteristics needed to cope with the high strength, high temperature and durability conditions required by particular strategic industries.
