YOUR FRIENDLY GUIDE TO ALL THINGS BRASS
I am Sonny, and I did not grow up around brass — nobody in my world handled it. So I learned it from zero, and this is the guide I wish someone had handed me on day one: every brass topic, in plain language, with nothing to sign up for.

THE SHORT VERSION
TL;DR
Last updated: October 2026
- Brass is copper plus zinc. That is the whole recipe — and the ratio of the two decides the color, the hardness, and the name.
- This is the Friendly Guides hub for all of it: the science, the alloys, where brass hides, the trades and hobbies it runs on, identification, and the money.
- Pick your lane below: Beginner, Working Pro, Veteran, or Master. Each path lists the guides in the order I would read them.
- The naming mess is real and we tell it honestly: "red brass" sits near bronze, and "architectural bronze" is actually a brass.
- The money lesson is worth learning first: brass is worth real money as scrap, it follows the copper market, and most of it gets thrown in the trash.
- Everything here is free, written in plain language, and checked against the UNS alloy system and real trade practice.
- Every page ends with "When the brass comes out" — what brass scrap is honestly worth, and one number to call when you are ready to sell.
START HERE
Four learning paths. Pick your lane.

QUESTIONS, ANSWERED
Brass guide FAQ.
What is the Friendly Guide to All Things Brass?
It is the hub page for everything brass on this site: the science, the alloys, where brass hides, the trades and hobbies it runs on, identification, and the money. The guides are organized into four learning paths (Beginner, Working Pro, Veteran, Master) and five tracks, so you can start at your level and read in order.
Who is this brass guide written for?
Curious readers, homeowners doing cleanouts, plumbers, machinists, band instrument repair techs, reloaders, shop owners, and anyone who has ever held a golden fitting and wondered what it is. Each path sequences the guides for a different level, so a beginner and a veteran can both find their starting point.
Is everything in the brass guide really free?
Yes. Every guide, chart, and tool in this hub is free to read with no sign-up and no paywall. The guide is supported by our scrap-buying business: we buy brass scrap from the same shops, plumbers, and sellers these guides are written for.
You do not look like a brass guy. Why should I learn brass from you?
That is the whole point of the guide. Sonny did not grow up around brass and nobody in his world handled it, so he learned it from zero and wrote the guide he wishes someone had handed him on day one. The newcomer who learned it carefully is the one who checks every fact twice, and the reader learns alongside him.
Where should I start reading?
Start with the Beginner path: What Is Brass, then History of Brass, then How Brass Is Made, then Brass vs Bronze. That order takes you from zero knowledge to the naming honesty lesson in under an hour.
Is brass worth anything as scrap?
Brass is worth real money as scrap, and it follows the copper market up and down. Most of it gets thrown in the trash anyway: valves from repipes, fittings from remodels, buckets of range brass. We never publish per-lb prices here, but one call gets you today's number on your pile.
What is the difference between the brass guide and the sell-brass-scrap page?
The brass guide is the learner's front door: knowledge, trades, hobbies, and science. Sell-brass-scrap is the seller's front door: the pitch, the phone number, and how selling works. They link to each other but serve different questions, so we keep them separate.
Can I suggest a brass topic for the guide?
Yes. If there is a brass topic you want explained, a comparison you want settled, or a procedure you want walked through, call or text 312-880-8174 and say what you need. The guide grows based on what readers actually ask for.

WHY I WROTE THIS
A note from Sonny.
I did not grow up around brass. Copper I knew from the wire days, carbide I learned on the scale — but brass was nobody's metal in my world, so I had to learn it from zero. I read the alloy specs, I talked to plumbers and reloaders, I sorted the piles myself, and I wrote the guide I wish someone had handed me on day one. No vendor pitch, no textbook dryness — just the whole brass story in plain language.
If you read one page here and it saves you a mix-up or puts money in your pocket, it did its job. And when the brass comes out, you know my number: 312-880-8174. I will take it from there.
