- Rockin’ Patent: US Patent No. 9,117,423
- Filed: 8 January 2014
- In the name of: Ernie Ball Inc
- Title: Aluminum Copper Wrap Wire For Musical Instruments
- What’s claimed: “A string for a musical stringed instrument comprising: (a) a core wire; and (b) a wrap wire coiled tightly around the core wire, the wrap wire comprising an aluminum-copper alloy comprising between about 2 wt % and about 10 wt % aluminum.”
- Why this patent rocks: This patent appears to involve Ernie Ball Inc’s aluminum bronze wire tailored for Ernie Ball acoustic guitar strings. Brian Ball, vice president at Ernie Ball, claims that “the wire alloy, weight-accuracy and temper make a big difference in the tone and performance of our guitar strings.” LightMetalAge writes that the aluminium-bronze blend provides more protection and clarity than traditional bronze strings, as well as improved corrosion resistance.
