Choosing the Right Material: 4 Tips (Updated for 2023) | ASM

Choose the Right Material to Speed Up Lead Time for Precision Sheet Metal Parts (Updated for 2023)

Last updated on November 9th, 2023 at 09:51 am

In the world of manufacturing, every minute of lead time matters. Developing a new product involves many moving parts (literally)—and no one wants to be the one responsible for bogging down a production timeline.

There are plenty of strategies for expediting production, but when it comes to getting precision sheet metal parts fast, it’s critical to ace the very first step in the process: choosing the right material.

Choosing the Right Material: 4 Tips for Quick Turn Sheet Metal Parts

When selecting custom sheet metal for a part, factors like weight, corrosion-resistance, strength, machinability, and availability are all important—and they all can affect lead time.

If your project allows you some material flexibility, these strategies can really help speed up the process and get you your parts much faster.

Lead Time Accelerator #1: Choose a material that doesn’t require finishing.

Selecting a material that already has the cosmetic or functional properties you need can improve lead time significantly.

Many of our customers ask for steel with zinc, but zinc plating can take up to 3-5 working days. If you need a corrosion-resistant part and there will be no welding involved, we suggest a galvanized material instead. Need your part to look aesthetically pleasing? Try stainless steel—especially for low volumes.

Sometimes it’s impossible to avoid finishing. Aluminum is prone to rust or decay in certain conditions, and the only way to avoid corrosion is by anodizing the part or adding a chromate coating.

But if you’re making a show or demo part that will only be used indoors, you don’t need those finishing processes. You can skip the finishing altogether or upgrade to a material that already has the properties you need baked in.

Lead Time Accelerator #2: Choose stainless steel if your parts need welding.

Galvanized or pre-plated steel isn’t safe to weld because it creates a poisonous gas that’s harmful to the person welding it. In addition to safety concerns, welding removes the coating on the material, which can cause the material to rust post-welding.

Because it’s not as strong as other steel, galvanized steel also has a tendency to distort when welded.  Making the proper accommodations to avoid this distortion can eat up a lot of prep time. For an alternative, we recommend stainless steel for welding. A nice 074 stainless steel will weld at 3 inches per minute, which makes up for the extra material expense. Plus, it won’t warp on us!

Lead Time Accelerator #3: Choose the right gauge.

Don’t scour the ends of the earth looking for a stainless steel gauge that doesn’t exist! Gauge charts are helpful, but they don’t give you any insight into the actual availability of the material you’ve chosen. For intel on which materials are relatively easy or very difficult to source, look to ASM’s team to make expert recommendations.

For example, 8 or 9 gauge steel may exist on your gauge chart, but in practice, it’s nearly impossible to find. We’ll usually advise customers looking for quick turn sheet metal parts to go with 7 or 10 gauge steel instead.

Lead Time Accelerator #4: Choose a material from our Same Day Materials List.

If you’re on a really tight schedule, select a material from our Same Day Materials List so we can turn your part around super fast. We can even get you flat sheet metal parts the same day with our Same Day Rush Service.

Sheet Metal Fab Material FAQ

Selecting the right material is the first step in expediting production for precision sheet metal parts. Factors like weight, corrosion-resistance, strength, machinability, and availability impact lead time. Choosing a material that aligns with your project needs can significantly speed up the process.

Opting for a material with existing cosmetic or functional properties eliminates the need for additional finishing processes. For instance, choosing galvanized steel for corrosion resistance, instead of steel with zinc that requires plating, can save 3-5 working days. This lead time accelerator is especially useful for projects where finishing processes are unnecessary.

Galvanized or pre-plated steel is unsafe to weld due to the creation of harmful gases and the removal of coating, leading to post-weld rusting. Stainless steel is a safer alternative for welding, as it welds efficiently without compromising strength. Choosing the right material for welding can save time on safety precautions and prep work.

Gauge charts may not provide insight into the actual availability of materials. ASM’s team offers expert recommendations based on material availability, guiding customers towards options that are relatively easy to source. This ensures quick turn sheet metal parts by avoiding the search for gauges that are challenging to find in practice.

The Same Day Materials List is a selection of materials that can be processed quickly, enabling us to turn around sheet metal parts on the same day. Choosing a material from this list, especially with the Same Day Rush Service, ensures rapid production for projects on tight schedules.
