ALUMINIUM - FORMODAL60

ALUMINIUM SHEETS and PLATES

  TECHNICAL INFORMATION   

FORMODAL60 is a new aluminium material, which is designed for mould, pattern and tool manufacture. 
The specification of this alloy is :
- excellent stability over the whole thickness of the plate (so also in the centre area)
- a very good cutting quality (with high cutting speeds)

Suggestions for processing :
The best relation of the rates of feed for drilling and turning are between
0.1 and 0.5 mm/n. For milling the value per cutter is between 0.05 and 0.1 mm

Cutting tools are recommended, which are used for short chip breaking materials
(e.g. stainless or structural steel processing)

milling: roughing as high as possible ** 0.05 - 0.10

drilling * as high as possible ** 0.10 - 0.15 
per cutter		 yes for short chipping

for long chipping materials
thread cutting yes
thread moulding yes

* for drillers of 6 mm        ** for cutting speeds under 500 m/min.

Further physical qualities :

electric conductibility :                    m/ohm mm2  = 19 - 23
caloric conductibility :                     1/10° K=23,4
heat expansion :                            W/m K = 130 - 160
modulus of elasticity :                     n/mm2 = -71000

advantages 

disadvantages
++ high-tensile material
++ continuous high stability - even in the centre of thick plates
++ very good cutting quality
++ to erode (copper-electrode) 
  + anodic oxidation for protection, 
  + to nickel-plate chemically, 
  + to coat galvanization		 - low corrosion - resisting
- internal stresses (warping possible)
- welding, soldering

Explanation : ++ = very good,  + = good to sufficient,  - = not suitable
