Aluminum Needles

Transmet’s Aluminum Needles offer power and strength to meet all industrial purposes. They are cast in a proprietary centrifugal air atomization process, meaning that they are clean and dry and lack any oils or dust.

Thanks to a consistent casting process, Transmet’s aluminum needles are able to maintain a reliable size and shape. Transmet’s aluminum needles serve a number of purposes, improving several key industrial processes.

Past Applications for Transmet’s Aluminum Needles

Binder for master alloying products produced by briquetting

Aluminum needles are the perfect binder for master alloying products.

Needles enhance thermal conductivity in epoxy molds

Thermal conductivity of a standard unfilled epoxy system is on the low side. With help from aluminum needles, this conductivity can be greatly enhanced.

Feedstock for chemical reactions

Our aluminum needles are excellent facilitators of chemical reactions.

Ingredient in drain cleaners

Aluminum is a chief ingredient within drain cleaners to help create the optimal chemical formula.
