CNC machining material selection, machinability, properties, and application guides.
UNS C71500 — copper-nickel 70/30, written CuNi 30 and matching the European grade CuNi30Mn1Fe (CW354H) — is the stronger, more erosion-resistant sibling of the 90/10 cupronickel
USITC imposed antidumping and countervailing duties on silicon metal from Australia and Norway on August 3, 2026. Here is what higher silicon costs mean for 6061, A356 and aluminum CNC part pricing.
If you are specifying a wrought silicon bronze for CNC-turned or milled parts that need good corrosion resistance, moderate strength, and tighter budget control than aluminum bronze, C66100 (C…
Aluminum prices reached $3,336.50 per tonne on August 10, 2026, up 29.1% year-over-year, as supply constraints tighten across global smelting operations. Non-China output fell 6.7% in July, LME inventories hit their lowest level this century, and Alcoa cut its production forecast following operational issues at an Australian refinery.
Take C65100 silicon bronze — a workhorse in marine fasteners and electrical connectors — and push the silicon content from roughly 1% to about 3%. Add manganese. The result is C65500, sometimes called
On July 23, 2026, the National Institute of Standards and Technology (NIST) released a Notice of Funding Opportunity (NOFO) to establish Manufacturing Extension Partnership (MEP) centers in 14 U.S. states and Puerto Rico, with total authorized fundin…
If you are choosing between C63000 and C63200 for a turned or milled component that lives in seawater and carries heavy cyclic loads, spec C63200 when the failure mode you are guar…
C61400 aluminum bronze (CuAl6Fe2): mechanical properties per ASTM B150, CNC turning and milling parameters, seawater corrosion data, and comparison with C63000 for marine parts.
This article references authoritative data from the Metals Materials Encyclopedia to provide a detailed analysis of the performance characteristics and processing applications of H13 hot w
C54400 leaded phosphor bronze (CuSn4Zn4Pb4) combines moderate strength with ~4% lead for self-lubricating bearing performance. Covers ASTM B139 tempers, mechanical properties, CNC machining parameters, and RFQ checklist for bushings, thrust washers and worm gears.
C51900 CuSn6 phosphor bronze sits between C51000 and C52100 in strength and formability — the ideal grade when C51000 lacks spring force but C52100 is too stiff to form. This guide covers composition, temper selection, CNC machining behavior, and what to specify on your RFQ.
Material Identity and Specification Family 7049 was registered with the Aluminum Association in 1968 as a high-strength Al-Zn-Mg-Cu forging alloy within the 7xxx series. Its UNS designation is A97049;…
World Steel Association June 2026 data shows global crude steel production at 155.7 Mt (+1.7% YoY), but regional divergence — North America +5.0%, Middle East -13.4% — creates uneven material availability for CNC-machined steel components. Buyers should verify mill origins and adjust sourcing strategies for H2 2026.
6101 aluminum is an electrical-grade 6xxx alloy designed for bus bars and power distribution components. Learn material selection, machinability, and RFQ requirements for CNC-machined 6101 parts.
If you are machining a structural aluminum part that will operate between 150°C and 250°C and you need more strength than 6061-T6 but better machinability than 7075 in the hardened condition, 2025 alu…
worldsteel published its climate policy paper on 19 July 2026, mapping steel decarbonization pathways. What CNC machining buyers should know about carbon surcharges, mill certification changes, and grade availability.
If you’re designing a part that will be formed, bent, or deep-drawn before or after machining — and it doesn’t need 6061-level strength — 3003-H14 is usually the right starting point. Its ~1.2% manganese addition gives it roughly 10–20% more strength than 1100 commercially pure aluminum without s…
China’s NDRC energy-conservation mandate (July 2026) tightens steel supply for CNC machining. Buyers should audit mill sources, review CBAM exposure, and lock in H2 pricing. Analysis with worldsteel data.
20 steel is a high-quality carbon structural steel under the GB/T 699-2015 standard, with a carbon content of approximately 0.20%, classified as low-carbon steel. It offers moderate strength, excel
When to Use 6016 Aluminum in Machined Parts — and When to Walk Away If your part starts as sheet metal and finishes with CNC machining, 6016 deserves a hard look. This 6xxx-series alloy was engineered…
