In high-volume metal fabrication, the performance of your equipment is only as strong as its cutting edge. Metal shear blades serve as the heartbeat of your production line—and off-the-shelf options often fall short when tasked with specialized materials and unique operational demands. This is where investing in high-quality, precision-engineered custom blades becomes a transformative game-changer for modern industrial applications.
Every metalworking shop has distinct requirements, ranging from shearing thin aluminum sheets to heavy-duty stainless steel plates. Standard, one-size-fits-all blades often lack the precise clearance or optimal rake angle needed for specific tasks, leading to subpar results and unnecessary machine stress. By choosing custom blades, you ensure the tool’s geometry is perfectly calibrated to your material’s thickness, tensile strength, and unique properties—delivering cleaner, more consistent cuts while reducing strain on your equipment and extending its service life.
The key to long-lasting, high-performance metal shear blades lies in superior metallurgy. Premium custom blades are crafted from shock-resistant tool steels—such as D2, H13, or S7—selected for their exceptional durability and performance under pressure. These high-grade materials undergo advanced vacuum heat treatment, achieving the ideal balance between hardness (to maintain a sharp, reliable edge through repeated use) and toughness (to resist cracking, chipping, or deformation under high-impact industrial conditions).
While the initial investment in custom blades may be higher than off-the-shelf alternatives, the long-term return on investment (ROI) is undeniable. Precision-ground edges eliminate the need for time-consuming secondary finishing processes, while superior wear resistance extends the intervals between regrinding and blade replacement. For critical industrial operations, this translates to less unplanned downtime, lower maintenance costs, and a significantly safer working environment for your technicians—all of which drive greater efficiency and profitability.
Whether you’re upgrading an existing machine or designing a new metal fabrication process, your choice of metal shear blades directly defines the quality, efficiency, and reliability of your output. Don’t settle for “good enough”—opt for high-quality, precision-engineered custom blades designed to excel in the toughest industrial environments and give your operation a distinct competitive edge.

ALAS blades are typically made from materials such as 9CrSi, 6CrW2Si, Cr12MoV, H13, H13K, and LD. The blades have a rectangular cross-section and a hardness of HRC50 to 62. They provide high-precision, burr-free cutting surfaces. Customization according to drawings is available.
The following table summarizes the type, core characteristics and main applicable shearing materials of common blade materials:
Blade Material | Material Type | Characteristics | Main Shearing Materials |
9CrSi | Alloy Tool Steel | High hardness, high wear resistance, small quenching deformation, high cost performance | Thin cold-rolled plate, galvanized plate, aluminum plate, copper plate; non-metallic materials such as plastic and leather |
6CrW2Si | Alloy Tool Steel | Contains tungsten element, excellent red hardness and wear resistance | Hot shearing operations materials, light stainless steel, medium strength steel |
Cr12MoV/SKD-11 | High Carbon High Chromium Steel | Excellent wear resistance and hardenability | Stainless steel, silicon steel, high strength steel, low carbon steel of various thicknesses, Q235, aluminum plate, copper plate |
H13 (4Cr5MoSiV1) | Hot Work Die Steel | Excellent high temperature strength and thermal fatigue resistance | Hot-sheared hot rolled plate, iron plate, medium and thick plate, scrap metal, hot-sheared strip steel, cold-sheared high strength alloy steel, stainless steel thick plate |
Cr12Mo1V1/ D2 | High Carbon High Chromium Steel | High strength, good wear resistance, excellent chipping resistance | Stainless steel, high strength steel, silicon steel, medium and low hardness plates (Q195/Q235/45# steel / 40Cr, etc.), aluminum / copper / brass / red copper plate; non-metallic materials such as plastic / rubber / paper / fiberboard, composite materials |
LD (7Cr7Mo2V2Si) | Cold Work Die Steel | High strength, good toughness, wear resistance and chipping resistance, excellent comprehensive performance | High strength steel, stainless steel, thick plate and hard-to-shear metal materials (for large hydraulic shearing machines, heavy CNC shearing machines) |
Powder Metallurgy Steel | High-end Alloy Tool Steel | Ultra-high hardness, extremely long service life | High-end composite plate, wear-resistant steel, high-end precision shearing metal materials (for high wear resistance and long service life requirements) |

Shearing light stainless steel and medium strength steel: Choose SKD11 and D2, which balance wear resistance and chipping resistance with stable shearing performance;
Higher blade hardness is not always better, and hardness and toughness need to be balanced: Excessively high hardness is prone to chipping, while excessively low hardness is prone to passivation. It is necessary to select reasonably according to the shearing material and operation load;
For the same material, the heat treatment process directly affects the performance: High-quality materials need to be matched with professional quenching and tempering processes to give full play to their advantages such as wear resistance and toughness;
For sticky knife materials (such as Stainless steel, titanium alloy, aluminum, copper and its alloys): Prioritize Cr12MoV and SKD11, which can effectively prevent knife sticking and chipping, and improve shearing efficiency and quality.
