Wedron Silica High Purity Silica

Wedron Silica High Purity Silica

Our high-purity foundry sand, with fine-tuned process control and consistent grade distribution, enhances operational efficiency. Our high-purity, round, 99%+ quartz sand is processed and sized with rigid adherence to Covia’s QIP statistical and quality assurance programs.


The round grain offers considerable value. The grain-to-grain contact with greater packing density improves casting quality with a better surface finish. The grain’s reduced surface area requires less resin to achieve superior tensile strength, and the high-purity grain’s hardness ensures lower attrition that increases sand reclamation.


Cleaner sand boosts your commitment to the team’s working conditions. Our sand is available from seven of our high-volume mines that are part of our strategic distribution network.


Features and Benefits

  • Improve casting quality with better surface finish
  • Impeccable process control for consistent grade distribution
  • High-purity 99% quartz sand

"Prior to our relationship with Weaver Materiel, we were purchasing riser sleeves direct from the OEM. As a stocking distributor, Weaver typically is able to deliver same or next day. OEM lead times averaged three to four weeks. With Weaver, I've been able to reduce my working inventory by about 40%."

“Ashland Foundry & Machine Works and Weatherly Casting are grateful for the partnership in our working relationship with Weaver Materials.  Weaver has helped us maintain pricing and avoid increases in a volatile market.  Weaver has always kept us in supply of material when markets dictated shortages/allocation status.  If Weaver was not in our vendor pool daily production ability would have been negatively impacted.  Weaver is also technically able to review our foundry processes and make suggestions to either achieve a cost savings or process improvement.  I am looking forward to a continued collaboration between the Weaver team and my locations.”
