John, We used Bendalloy at NASA, manufacturer unknown. It was good for potting items in place. It held tightly. It dampened vibration. Its worst characteristic was its tendency to expand as it cooled. When pouring it inside thin-walled items, it might expand enough to bust the piece. Because it was hot and expanded, it could change the size of thin aluminum pieces. After machining and melting the bendalloy out, the piece would be out of tolerance.
A favorite practical joke was to pour bendalloy around someone's wrench or other tool. Once it cooled, they would have to dunk it into the melting pot to get their tool back. Really mean people would pour it into someone's tool box. Twice, one guy unplugged the melting pot and dropped the plug into the pot. An electrician had to put a new power cord on the pot. I once poured bendalloy into a short piece of pipe to carry when I went to a bad section of town. I left it on the dash of my car one day, and all the bendalloy melted and ran into my speaker. Oops!
