Review: Good price. Fast delivery. Did not have to go store hoping. - Works good for clean brass job. Have used before. Review: A Quality Brazing Flux - I have been using Peterson #1 Blue Flux, Coarse Powder, for over 35 years. Not often, but once or twice a year, and have been satisfied in every way with it. My current can of flux is about 20 years old and is nearly gone. During that time it has remained unchanged in the can and works the same today as it did when purchased. About a year ago I purchased a pound or two of flux coated brazing rod and tried it out but decided I didn't like it because of the overabundance of flux accumulating on the item being brazed. The other day I noticed that much of the flux had peeled and fallen off the brazing rod that I had left over. In the future I will stick with Peterson #1 Coarse. It coats the metal being brazed and allows the brazing material to wet the iron or steel being brazed in a very satisfactory manner. I have had no problems with attaining high quality brazing jobs. ## Features - For brazing and welding cast and malleable iron and steel - For torch welding brass, bronze and copper - Working temperature 1200-1600F/650-870C - AWS Brazing Classification FB3-F - Coarser texture than Peterson #1 Fine ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 365 Reviews | ## Images ![Peterson #1 Blue Flux, Coarse Powder, 1 lb Can - Image 1](https://m.media-amazon.com/images/I/811AGt+h0gL.jpg) ![Peterson #1 Blue Flux, Coarse Powder, 1 lb Can - Image 2](https://m.media-amazon.com/images/I/51pATiOJ9XL.jpg) ![Peterson #1 Blue Flux, Coarse Powder, 1 lb Can - Image 3](https://m.media-amazon.com/images/I/71rNh2gDHgL.jpg) ![Peterson #1 Blue Flux, Coarse Powder, 1 lb Can - Image 4](https://m.media-amazon.com/images/I/51YVo3M4ruL.jpg) ![Peterson #1 Blue Flux, Coarse Powder, 1 lb Can - Image 5](https://m.media-amazon.com/images/I/61BFi2uOlgL.jpg) ## Questions & Answers **Q: How do you prepare this for use?** A: You dont have to prepare it. Open can and get brazing rod hot and dip it in open can. The flux will stick to it. Works great. you can control the amount you need and wet out the base metal as needed. Save you from worrying about you flux falling off of the flux coated rods... then you have no flux. No forget to periodically dip rod in flux to recoat. After a while you will get the hang of it. They also make a #2 i cant seem to find on amazon. Try ebay. Lyndell **Q: clean up removal of excess flux after welding is finished ?** A: Flux residue can be removed with hot water. **Q: Can this be used in blacksmithing?** A: It can be, but not best. The working temperature is for brazing, but Borax is used for brazing AND forge welding, but this has boric acid added to lower the working temperature for brazing. You can add a little ash to it to help with blacksmithing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good price. Fast delivery.

I had to deduct a star for the paper label. Whose idea was that, to put a paper label on a product that's intended to be used in close proximity to a very hot burning torch, especially if any of the info included on the label is important info ## Frequently Bought Together - Peterson #1 Blue Flux, Coarse Powder, 1 lb Can - Peterson #1 Fine Flux, Fine Powder, 1 lb Can - 5 Pack 12"x2"x0.12" 1095 Steel for Knife Making with Strict Quality Standards, The Perfect Knife Making Steel for Professional & Hobbyist Use, Annealed High Carbon Steel for DIY Knife Making --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/80641860-peterson-1-blue-flux-coarse-powder-1-lb-can](https://www.desertcart.tn/products/80641860-peterson-1-blue-flux-coarse-powder-1-lb-can) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-28*
