US distributor for Titanal

Post by Cadman »

Is there anyone who can tell me where to buy quantities of Titanal?
I am looking for .3 mm or .4mm.

Is there a substitute for Titanal since this is a brand name for aluminum
with titanium in it. I know that the main manufacturer is AMG Rolling. I was wondering if there was a distributor in the US.

Don't even think it has got any signifficant amounts of titanium in it. But if it does, may be it is some sort of tempered 7/8000 alloy?

its not the 7 or the 8000 series aluminums. those are alloyed with zinc and tin respectively. i have been looking for a designation for a AL alloyed with Ti and so far havent had much luck.

If you want specifics on TITINAL composition here is the data sheet I found on their website. There is no titanium in the alloy. If you want a look at the original document then check out the link from the links page on this site.

The phosphoric acid anodization is important because that allows the aluminum to bond well with adhesives.


TITANAL  (AlZn7MgCuZr), phosphoric-acid-anodized

AMAG rolling produces TITANAL phosphoric-acid-anodized in coils and sheets. TITANAL  is a high strength, age hardenable aluminium-wrought-alloy with pre-treated surface used in ski- and snowboard-construction, especially for load-bearing elements as top and bottom girders.

Mechanical properties (parallel to rolling direction)
Temper Thickness Tensile Strength 0,2- Yield Strength Elongation Brinell hardness
(mm) Rm (MPa) Rp0.2 (MPa) A5 (%) HBW2,5/62,5
T6 fully aged 0.4 – 0.6 app. 630  580  12 appr.172
T7 overaged 0.4 – 0.6 app. 600 540 - 580  12
T6 0.7 – 1.2 app. 650  600  12 appr.174
T7 0.7 – 1.2 app. 630 580 – 620  12

notch tensile strength = approx. 450 MPa

Glue ability
We examine glued surface (phosphor-acid-anodized-layer against phoshpor-acid-anodized-layer) with a stiffening on the climbing drum peel test in accordance to DIN 53 295. Adhesive Area: 50 x 250 mm

Adhesive substance: AW 1137, Accelerator HY5049 CIBA; mixture proportion = 100:30,
Glue apply = 100 g/m²; Hardening at 100°C/20 min, 3,8 bar = 283 kp

Whenever you are considering a new application for this alloy, which may require certain characteristics, we expressly recommend that you contact us concerning the careful selection of the material

In general
Anodizing in phosphoric electrolytes serve as surface pre-treatment for permanent gluing of
Aluminium and is successfully used in aircraft- and ski-constructions. Requirements on the decorative appearance cannot be guaranteed. Phosphor acid anodizing layers are extremely
thin and show a very good suitability for gluing because of it s open porosity (epoxy- and
phenol resin - adhesive). They do not contain organic components, they are non polluting and storable.

Storability
TITANAL&#61666; phosphoric-acid-anodized is without paper intermediate layers and delivered with silica gel (drying agent). The storage has to be made suitable for aluminium in dustfree and dry atmosphere (RT approx. 5 to 30°C). If you store the material longer than 6 months the surface may suffer.

Subsequent processing
The very thin layers (< 0.1 µm) are sensitive to mechanical damage. The surface has to be kept free from impurities and especially from dust, fingerprints (use clean leather gloves), grease and lubricants, as well as release agents (silicone papers, mould-release-agents) and moisture. Contour-milling and stencilling is possible without problems, however lubricants should not be used. Under consideration of these conditions deforming can also be made.

Behaviour under temperature
TITANAL&#61666;, phosphoric-acid-anodized, can be glued at usual temperatures (~140°C). Higher temperatures can result in a decrease of strength.
For that purpose we can transmit after request loss of cohesion curves. If you laminate one side or make lacquer coating please check the glueability of the remaining surface.

This specification is considered as guideline. The user must consider additionally its own manufacturing production lines. Further the processing plant must create the prerequisite over secure that the selected material for the application purpose is suitable.
