Analysis
NAICS 33142 is the 2022 NAICS industry for copper rolling, drawing, extruding, and alloying, part of 3314 (Nonferrous Metal (except Aluminum) Production and Processing).
It has only one more detailed code, 331420, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 211 US establishments in this code in 2023, employing 25,555 people at an average annual payroll of $78,043 per employee (66th percentile of national industries). 5% of the establishments have fewer than five employees, which points to larger operations.
Between 2018 and 2023 the number of establishments fell 10% and employment rose 2%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
By establishments it ranks 2nd of the 3 codes at this level within Nonferrous Metal (except Aluminum) Production and Processing, with 29.8% of them.
