Ti Grade 2 (TA2) and common alloy steels (4140, 4340) cover overlapping tensile ranges (200–1400 MPa) but diverge sharply on density (4.5 vs 7.85 g/cm³), seawater corrosion, and cost — Ti wins for weight- and corrosion-driven duty, alloy steel wins for cheap, hardenable structural parts.
CRGO silicon steel is the dedicated transformer core grade trading in mid-2026 around 1,800-2,200 USD/t for M2-M4 grades, while CRNGO motor laminations sit lower at roughly 1,100-1,500 USD/t, with grade, coating, gauge and mill origin the main price levers.
Silicon steel buying in 2026 hinges on grade family (CGO vs HiB vs grain-oriented 0.23-0.35 mm), core-loss class (e.g. 35W250, 30Q120), and ASTM/EN/IEC traceability; ASTM M-series sheets from Chinese mills remain the dominant wholesale SKU.
Silicon steel selection pivots on three hard numbers: silicon content band (typically 1–3.5% Si), lamination thickness (0.23–0.35 mm for CGO; 0.18–0.30 mm for HGO/HiB) and core-loss grade. Specifiers trade cost against watts-per-kilogram at 1.5 T/50 Hz before touching a quotation.
Engineers spec grey cast iron (ASTM A48 Class 20-60) for vibration-damping machine bases and ductile iron (ASTM A536 60-40-18 / 65-45-12) for structural castings; 2026 China ex-works FOB bands sit near US$700-1,200/t for grey, US$900-1,400/t for ductile.
Gray iron ASTM A48 classes 20–60, ductile iron ASTM A536 grades 60-40-18 through 120-90-02, and high-alloy Ni-Cr variants cover most industrial spec needs; selection hinges on tensile/yield/elongation, section thickness, corrosion environment, and machinability rather than a single "best" grade.
LME-grade copper cathode traded in a wide band across 2026 H1, with wholesale copper grit listings on Made-in-China spanning US$215-760/tonne and LME scrap (99.99% Cu) quotes clustered in the multi-thousand-USD/tonne range, while integrated mill offer prices for expanded sheet, bus bar and water tub
Copper grade selection hinges on UNS designation, conductivity band, impurity ceiling and form — CDA guides seawater Cu-Ni 90/10 and 70/30, while C11000 remains the dominant electrical busbar grade. Specification must lock UNS number, temper, dimensional standard and a defined corrosion envelope.
Aluminum alloy selection is governed by alloy series (1xxx-7xxx), temper (O, T4, T5, T6, T7), mechanical envelope (tensile/yield/elongation), corrosion environment, weldability and formability. Mismatch on series-vs-process wastes billet and tool life.
304 stainless steel sheet trades at US$1,440-2,250 per ton on China wholesale platforms as of June 2026, with plate and coil price spreads tied to grade, finish and order volume.
Alloy steel delivers tensile strength above 800 MPa and high-temperature endurance above 600°C, while aluminum alloy cuts component mass by roughly 60% versus carbon steel; the right pick depends on strength-to-weight ratio, corrosion regime, thermal load and cost-per-kg at the order stage.
Alloy steel selection hinges on matching hardenability, carbon content (0.25-0.60% C typical for structural grades), and alloying system (Cr/Mo/Ni/V) to service conditions — load, temperature, corrosion, and weldability — with AISI-SAE grade families and hardenability bands (H-band) driving the call
