Regular aluminum doesn't hold pitch as well as steel due to its "softer" nature. however, temperd aluminum is different. Once heated, it gains rigidity and a greater tolerance to hold frequency. It becomes a better medium then which is accurate and sustains longer that steel with powerful overtones and harmonics.

Also of interest to note, Jonothan Goldamn, who I consider one of the most aware humans when it comes to healing with sound, uses aluminum tuning forks, Their overtones and harmonics are "magical."

Here is an excellent site for all kinds of tuning forks for healing work as well as other applications. They also make wind chimes. I shared my idea of having a solfegio windchime with Horowitz (based on Puleo's work) and this company put the idea into action.

Another thing to consider is a bio tuner that you can program any pitch or combination of pitches to use in sound therapy (also does binaural beats) and it is relatvely inexpensive. In conjunction with voice analysis software, this becomes a powerful energetic tool.

You can also use a transducer in conjuction with a tuner and imprint homeopathically clear water with a specific frequency. The possiblilites are endless.
