Services Alloy Heat Treatment Provide



This is a process required for strengthening and machinability.


Immediately following solution treatment certain parts require rapid quenching. This involves a controlled quench in times of less than 10 seconds to ensure that quenched parts lose or expel minimal temperature between the furnace the quench bath.


This process removes the quench distortion from solution treated parts. We can set to close tolerances in a tight time frame at quench stage. This process can be extended to the rectification of parts distorted during general manufacturing.


Our Hanger Blast facility is used to give the product a uniform colour or appearance, such as a silvery matt finish, which will be visible in the finished product.


This heat treatment process is generally undertaken between 100 and 200 ºC and causes dissolved alloying elements to finely precipitate within the aluminium. This results in the alloy becoming harder and stronger.


We are able to verify the conformance and batch uniformity of heat treated parts, particularly for the aerospace industry. This is all done by level 2 certified operators using machines certified to UKAS standards.


This technique is used to detect cracks or flaws in heat treated parts. This is offered to customer requirements upon request.


Nadcap accredited for the micro examination and evaluation of heat treated parts in accordance with specific industry standards.


Our in house SED compliant solvent degreaser is capable of cleaning and drying components up to 3m long and 500 kilos in weight, to aircraft industry standards.


Alloy Heat Treatment offers this as a standard sub contracted service


We are able to offer a swift delivery or collection service via courier or haulage contractors to suit customer needs.
