I used that method with stiff aluminum wire for a while, and also made use of soft aluminum wire. As a note, the titanium wire sold by Caswell is quite soft, and doesn’t have a lot of stiffness. But it will work harden by bending enough, or cold working with a hammer, so it can be made into smaller clips with adequate spring qualities. It doesn’t appear to heat treat well as a hardening option.
I like the titanium racking a lot, the picture below is some I bought from Servisure. While it might seem kind of expensive at a glance, the hassle it removes from the entire anodizing process makes it an excellent value in my opinion.
The four sided finger rack is meant for doing more parts than a hobbyist is likely to need, but the other modular clips and angles to bolt them too are ideal for a few parts at a time, and provide quite a bit of versatility and configuration options. I'm just going by memory, but they are about $2-$3 each, the perforated angle to bolt them to is about a $1 an inch, and then a bolt and nut are less than a buck if I remember correctly.
The titanium clips can be reformed (within reason, of course) to fit the need, so you don't need to worry about the measurements fitting the part exactly; they just need to be within range. On large parts I may use 2-3 clips per part to secure the part and increase the electrical contact areas.
The angle can be configured with one or two risers, and by configuring it with a base to make it freestanding you can move it from tank to tank without the hassle of hanging it. That makes it much easier to handle the parts without touching them accidentally, or dropping them.
