A horizontal hydraulic press for hot aluminum extrusion (loose dies and scrap visible in foreground) There are many different variations of extrusion equipment. They vary by four major characteristics: [1] Movement of the extrusion with relation to the ram. If the die is held stationary and the ram moves towards it then it is called "direct ...

Material of the profile to be extruded plays an essential role in determining process parameters and potential limitations of a process. For example, minimum thickness of extruded carbon steel sheet is 3mm whereas same sheet of aluminium can be extruded into minimum sheet thicknesses of 1mm.
Typical material properties for 6005 aluminium alloy include: [2] Density: 2.70 g/cm 3, or 169 lb/ft 3. Young's modulus: 69 GPa, or 10 Msi. Ultimate tensile strength: 190 to 300 MPa, or 28 to 44 ksi. Yield strength: 100 to 260 MPa, or 15 to 38 ksi. Thermal Expansion: 23 μm/m-K.
6105 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the least common of the alloys in this series. While most wrought aluminium alloys are covered by multiple standards (from any mixture of ASTM, EN, ISO, and national standard bodies), 6105 is only dealt with in ASTM B221: Standard Specification for Aluminum and Aluminum-Alloy ...
After going through this process the properties of the material used are altered. Its hardness and yield strength are increased, cross-sectional area is decreased, some residual surface stresses will be present and micro cracks may appear. Physical and chemical properties are only influenced slightly.
In steel extrusions, the depth of an indentation should be no greater than its width at its narrowest point. This is necessary to provide sufficient strength in the tongue portion of the extruding die. In copper alloys, magnesium, and aluminum, the depth of an indentation may be greater since extrusion pressures are lower.
6082 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the more popular alloys in its series (alongside alloys 6005, 6061, and 6063), although it is not strongly featured in ASTM (North American) standards.
