Every machine shop has a scrap bin. Drops of 6061-T6 aluminum plate, remnants of 304 stainless round bar, half-used boxes of carbide end mills. Most of it sits on a rack until someone hauls it to the recycler for pennies on the dollar.
Meanwhile, the shop across town is placing a $1,200 order from a distributor for that exact same alloy, waiting five to ten business days for delivery, and losing a week of production time on a job that could have shipped yesterday.
This is the problem Calloy solves.
Calloy is a local marketplace purpose-built for machine shops. Sellers list surplus material, tooling, and consumables. Buyers search by alloy, dimension, and distance. Transactions happen locally, often same-day pickup, so you skip the distributor lead time entirely.
We started by talking to shop owners in Orange County, California. The pattern was consistent: shops carry $10,000 to $50,000 in surplus material at any given time. They know other shops nearby have the same problem, but there is no efficient way to discover what is available. Craigslist is too general. Industry forums are too slow. Calling around wastes hours.
Calloy gives every shop a digital storefront for their surplus. List a material in under two minutes with a photo, alloy grade, dimensions, and price. Buyers see listings on a map, filter by category, and message sellers directly. When both parties are ready, payment goes through Calloy with Stripe Connect, so funds are tracked and both sides are protected.
We are not trying to replace your primary distributor. When you need fifty sheets of HR 1018 steel, you call your rep. But when you need a 12-inch drop of 17-4 PH stainless for a prototype, Calloy gets it to your shop floor in hours instead of days.
The marketplace is free to browse and list. We only charge a small transaction fee when you use our integrated payment system. No monthly subscription required to participate.
We are launching in Orange County with a handful of committed shops and expanding from there. If you run a machine shop and want to turn your scrap rack into a revenue stream, list your first item on Calloy today.
