Improve Product Performance with High Purity Alloys
For many industries, higher quality alloys yield better connections, better assemblies, longer life and more predictable product performance. Lucas-Milhaupt manufactures high purity alloys to meet your most stringent requirements. How are high purity alloys formed? What applications benefit from their use? What types of high purity alloys are available? Join us for answers to these key questions.
High Purity Alloys → More Predictable Product Performance
In today’s quality-conscious world, product performance often comes down to the tiniest details. These details include joints and connections that create assemblies – and the alloys that hold them together. Impurities can form microscopic leak paths. Purer alloys mean better connections, better assemblies, longer life and more predictable product performance.
Lucas-Milhaupt’s high purity alloys are produced with the tightest impurity levels. This is imperative for systems that require vacuum tight seals and the highest levels of quality and reliability.

Forming High Purity Alloys
Lucas-Milhaupt manufactures high purity alloys under highly controlled processes to meet your most stringent requirements. Lucas-Milhaupt adheres to this quality-assured process:
-
Melt and cast alloys in a controlled environment to ensure purity and cleanliness from oxides, high vapor pressure elements and other contaminants
-
Verify alloy chemistry analysis to detect any impurities, ensuring reliable performance
-
Further process, under tight controls, to roll and slit for strip products or wire drawing
-
Fabricate each item into its final form – bulk, preform rings or stampings – and pack for shipment
-
Maintain cleanliness throughout the process to prevent introduction of impurities into the product or process
-
Final quality check, at finished size, to verify dimensional accuracy and performance.
Applications for High Purity Alloys
The brazing products industry developed these alloys to satisfy rigorous demands for high purity materials in forming reliable subassemblies. High purity assemblies have applications ranging from aerospace to medical technology to to telecommunications.
These components depend on brazed connections that must perform to specific expectations, maintain vacuum seals, cycle through heat and load and resist the corrosion that leads to failure. Product design, process development and control, and supplier performance must come together to ensure an optimal product life cycle.
Finding the Right Product
Lucas-Milhaupt has perfected the process of manufacturing high purity alloys. We provide our Premabraze® alloys in gold, silver and palladium with trace elements less than 1 part per million. These alloys are vacuum-grade filler metals that have compositions specifically controlled to fabricate joints exposed to high vacuum on electronic devices. Choose from a wide array of high purity alloy preforms, powder and paste products. These alloys meet ISO 9001: 2008 for quality and ISO 14001 for environmental management. You must braze these alloys in high purity atmosphere or vacuum.
Our Premabraze certified “pure” metals are vacuum melted and cast to ensure material cleanliness. You are assured of conformance to specification by chemical analysis and relevant performance requirements.
