Aluminium, Anodised Purple Kitless Fountain pen

[BradG]

Handmade with aircraft grade aluminium, and anodised purple, featuring a German JoWo Nib

Will be half a dozen colour variations of the same pen over the next few days, so il just post them as replies on this thread rather than creating a new post for each one.

Very attractive. The overall presentation is superbly professional. The color is also very appealing to me.

Very nice presentation. Look forward to see the others.

Looks stunning Brad. I love that colour.:biggrin:
What's the deal with calling it 'Aircraft Grade' ? Have you heat treated it or something? is this just a selling point or is it much better than non-aircraft grade stuff?

Generally, it's a sales spin Steve. It's alloy 7075 which is used for making aircraft pieces (hence aircraft grade) as its stronger than 6061 and doesnt dull the same. Usually id omit such talk from these forums though the description is copied and pasted from elsewhere

7075
Aircraft manufacturers use high-strength alloys (principally alloy 7075) to strengthen aluminum aircraft structures. Aluminum alloy 7075 has Copper (1.6 %), Magnesium (2.5 %) and zinc (5.6 %) added for ultimate strength, but the copper content makes it very difficult to weld. On the other hand it anodizes really beautifully. 7075 has the best machinability and it will result in a very nice finish.
Ultimate strength is 33000 PSI (-0) and 82000 PSI (-T6) with a shearing strength of 22000 PSI (-0) and 49000 PSI (-T6).

I'm sure you can see which part of that description, is what makes 7075 appeal to me :wink:

Aircraft Grade.

I also like the pen and presentation a lot. While you were responding I was going off on you for the marketing buzz words. Even though the alloy is the same as that used in aircraft it doesn't have the same quality requirements that follow the metal from the mine the ore comes from to the flying aircraft it ends up in. Sorry for the little rant but the marketing drives me batty. I'm also not good to sit with during a movie that involves airplanes.

Calm yourself Pete :biggrin:

You should give 2024 a go. Stays shinier, longer than 7075.
