Looking for the definition of miniature aluminum extrusion, we found the closest reference to micro extrusion in the aluminum association standards and data (the aluminum association's largest and most comprehensive publication).There, we found "precision" tolerances:

 

Instead of CNC machining technology, the efficiency of micro aluminum parts is increased by more than 50 times.

CNC machining of micro aluminum parts is the most difficult to adhere to the knife, knife thick processing product precision can not be guaranteed.However, the continuous die cold extrusion micro aluminum parts just avoid these disadvantages, and the processing precision is no less than CNC, can achieve ±0.02mm tolerance and processing speed of up to 150 per minute.Therefore, it is better to adopt the method of continuous die cold extrusion for the processing of miniature aluminum parts.

What are microextrusion aluminum profiles or microextrusion tubes?

A very broad definition is any aluminum extrusion or tube suitable for a circle of 5 inches in diameter (i.e., a 5 inch press).The choice of aluminum alloy is very important for this kind of complicated miniature extruded parts.Alloy 6063 is the shape of choice.

The smallest miniature extrusion piece is suitable for a circle with a diameter less than 100 inches.They require uniform wall thickness and require simple geometric design and specialized tools.Instead of using H13 tool steel, the special tool is made by using a powder metal process and depositing a specially developed coating on the surface.The coating helps the aluminum flow through the mold and resist wear.The 1100 and 3003 are also the most important alloy choices, the easiest to get through the mold and the easiest to get.
