|We get asked this question a lot: Why do your forks cost more than the ones I see on Ebay, or on some other websites? Let us show you the difference!
First, not all metals are created equally. There are many types and grades of aluminum alloy which are used for many different purposes. Typical alloying elements are copper, magnesium, maganese, silicon, tin, and zinc. These different alloys are used in combination to add strength, corrosion resistance, ductibility, etc. Aluminum Alloys can be divided into two classifications - casting aluminum, and wrought aluminum. These classifications can be further sub-divided in heat-treated, and non-heat-treated.
What Is The Difference?
Casting aluminum is a lower melting point alloy that is poured into a mold from a molten state. The mold is often made out of sand, and can be used over and over again, thus making the process inexpensive. Cast aluminum has a lower tensile strength and is very cost effective to produce. The most common additives used in this process are silicon and zinc, which adds some strength to the mixture and allows for a smooth casting process.
Wrought aluminum is a very high demanding metal, commonly used where even greater strength is needed (aerospace), along with corrosion resistance and ductility. Instead of pouring molten metal into a mold, it is extruded, rolled, or pounded, (wrought) into various solid shapes. The most common additive is magnesium, which gives it a great deal of strength. Aluminum-Magnesium alloys are lighter than other aluminum alloys. The wrought metal is formed into uniform bars, sheets, plates, etc. for specific applications. The entire process is much more costly but produces a very different product.
Why Does This Matter?
Our tuning forks are NOT made from cast aluminum, which is heavier and has a very poor finish. Instead, all of our forks are made from a heat-treated, lead-free, wrought aluminum alloy which has been chosen for its strength, light weight, and superior conductivity of sound waves. In addition, our forks have longer handles and shorter tines, keeping everything in perfect balance. No top-heavy forks here that will tire your hand!
We serve a professional sound healing community around the world and offer only High Quality Forks Made In the USA.
Every fork undergoes a special hand tuning process to assure accuracy within +/- .25%. And because the metal is heat-treated, it is tempered, making it very strong. The metal will not fatigue over time, and the forks will stay on frequency, even after years of use. We think wrought aluminum makes a superior tuning fork, and you can see, feel, and hear the difference.
